Re: Recuperar instalação

[G.Paulo]

Caros,

Obrigado a todos pelas dicas, especialmente a Francisco que enviou esse manual 
logo abaixo, que possivelmente servirah a outro em situacao semelhante.

Decidi instalar o sistema do zero (mas preservando o /home). Tudo certo. Exceto 
pela configuracao do teclado que, como se percebe, ainda nao tem acentuacao :-/

More the opposite. i.e. make the tail end of the long::name::thingy
identifiable in a _restricted_ scope. The :: nomenclature first appeared
(to my eyes) in C++ several decades ago. For perl to adopt an existing
convention is a step forward for the language.

Here's a brief exchange describing ::, the scope-resolution operator:

You mean those double colons ('::')?

If yes: those are just separators for the Perl module namespace, which
conceptually is a hierarchy. At the (right) end you can put some 
object

(function, variable) living in that module's [1] namespace.

Those are just a device to subdivide the namespace and to organize
file system "places" [1] -- they have no intrinsic "meaning" to perl
(i.e. the language itself has no notion of "Net" or "Net::DNS" -- just
of "Net::DNS::Nameserver").

Cf "perldoc -f require" for the full thing :-)

[1] In Perl parlance, it is a "package".
[2] Typically you'll find the package code in Net/DNS/Nameserver.pm
   under a suitable "module root", e.g. /usr/share/perl5. The whole
   list of roots is in the special array variable @INC.



I just happened to start noticing the same format being used within
"apt-cache show" query feedback, too. Took a second to find a good
example. This is for "openshot" (video editor):

Tag: implemented-in::python, interface::graphical, interface::x11,
 role::program, scope::application, use::editing, works-with::audio,
 works-with::video, x11::application

I THOUGHT I had searched "apt-cache" using those tags when I first
noticed them. It's not working that way now. It must have been that
the description's author had used the same categories as keywords in
their product description.

Am "feeling like" I've seen something where we could search by tags.
Sounds like a handy place for something like that to work.

Those tags would save at least a little bit on the false hits if you
were able to search for any packages with a developer expressed "use"
of "editing". Then you narrow that search to more specific usage needs
by seeking anything that "works with (consumes) audio (files)" which
is, in fact, something that has been a question on this list at some
point. Seems like that "interface" applied to that remembered thread
because the User was wanting something... command line. :D

That X11 tag, my memory's saying it feels like there was a question
where a User was seeking something that needed to specifically be
X11-friendly, too..

There's something to be said for the wide-open wing-it method, though.
Pick any keyword, and see what new find bubbles to the top. I searched
on "dragonfly" the other day while waiting for them to show back up

I am not 100% sure I am understanding you correctly, but the short
keyID for a gpg key is the _last_ 8 characters and not the 8 first -
With the key you describe above, the short keyID is C857C906.

This might be the cause of your confusion.

Try the pip python repositories

Just finished downloading all [tarballs], except maybe 1/2 of the
kernel, just last night. This is Round 2 for me. I got through Chapter
5 then #Life poked its nose into the mix.

Oh, and I just remembered... my brain blew a circuit over working
through the package manager process, too. I think of that frequently
when package manager questions come up here at Debian-User..

The testing part will be where I focus my curiosity this time. Do the
tests, yada-yada, keep on movin' on WHEN they fail. LOL. My memory is
that some of the "it's ok to fail" was that we hadn't installed
pertinent packages yet so there was no way it would ever not fail.

That repetition helps instill each point in the
compilation/installation process. The mantra back in early 2000's was,
"Eh, it's ok not to test, just keep going" That was talking about
compiling a single package on a pre-existing system.

If you follow the Linux From Scratch support list, you see why it's
not so ok. Occasional related user questions show typos and such would
have absolutely destroyed those users' entire install, thus wasting a
TON of time, had they either skipped testing or had they failed a test
and kept going anyway instead of questioning what failed. :)

Makes you a better advocate for doing things the right way.. I never
once md5sum'ed ANYTHING *ALL THESE YEARS*. As simple as the process
turned out to be, I could never find a HOWTO that made sense.

These days, that md5ums list is serving double duty by performing the
chore of instantly advising if packages are expired and need updated
simply because they don't get checked off as OK. Match any fails to
that HANDY wget-list that's also provided, and, chick-a-BOOM, you're
off and running toward Linux knowledge self-empowerment just that
quick (depending on Internet connection speed, of course of
course). :)

If you're beta testing the application, you may need to beta-test the OS
for it, too:

https://packages.debian.org/search?keywords=python3.7

python3.7 is available in testing.

Alternatively, if you want to be able to run python3.7 alongside your
system python, why not run it in a docker?

You mentioned that you considered LFS. If you have the time, that's
a real baptism of fire as far as compiling things goes. There were
automatic systems being developed when I was interested, but as far as
I can see, there's no point to LFS if you're just going to push a
button. I did it twice, mainly to learn what I could, with better
understanding the second time, the first try was basically just
following instructions. Lots of them. My firewall pseudo-daemon (until
systemd) was nicked from the basic LFS init script.

As it happens, the first Linux magazine I bought contained an article on
compiling kernels, so I did. Not until later did I find that it is
thought to be difficult. I didn't understand many of the modules, but
with a kernel, when in doubt say 'yes'. I think that was around Red Hat
5 (*not* RHEL).

Thanks for the pointer. I do not think it what I am looking for,
although it may be part of it.

What I am looking for is the HTML5 video-conference that is presented to
the user.

It will require a web-server, of course; this part I know how to handle.
I suppose it will also require some kind of connecting software,
possibly Janus or Janus+Asterisk. I expect it to be documented.

Basically, I would like to know all the software needed to build a web
page where a user can click on "call this person" and arrive to a
video-conference. This is vague: if I find something interesting, I will
be able to see what it can actually do and refine my question.

Obtaining/compiling/installing python3.7

[Richard Owlett]

I wish to try some beta software which assumes python3.7 is installed. I 
have Debian 9.8 installed on a machine dedicated to this exercise. I did 
a web search and got a half dozen on topic hits. There were enough 
differences that I wasn't sure if I was missing something important. The 
last time I compiled something was on a PDP 11/45 in approximately 1975.


Suggestions?

This probably won't be of great help.

Today's successful run, which removed probably most of the wheezy
packages in my cache¹, had the following error in the log:

Error at 
security.debian.org/debian-security/dists/stretch/updates/19704841552237202370979443

but it didn't stop the run. This file exists, but is actually at
/var/cache/apt-cacher-ng/_xstore/rsnap/security.debian.org/…
so take a look there perhaps.

The contents of the file look sane. Running a diff against the next
version showed that a fair number of files had been updated, and
the signature was completely different. However, that next version
and the one after that showed that the signature is always different
regardless of content, because there were no update differences in
the rest of the file.

These files go back months, and their timestamps seem to correspond
to the times when my   apt-get update   runs occur. So perhaps you
could try hiding the file and running the web interface again.

¹ I had to decrease ExStartTradeOff from 500m to 10m to give
expiration a push because jessie and stretch have been quite quiet
in the period since I removed all wheezy's apt-cacher-ng metadata.

Cheers,
David.

WebRTC is not one but a range of things.

Since you mention Asterisk, you are probably looking for an SFU - one of 
the best SFUs, Janus, is in Debian (maintained by me).  The contrib 
package janus-demos can be used as basis for custom applications aorund 
Janus.

Hi.

I would like some advice about good HTML5 WebRTC video-conference
software, preferably packaged by Debian, at least Libre and trustworthy.

Also, I would appreciate if it can do screen-casting too. Probably not
with a web browser client: A calls B from browser, B answers with a

There will probably be an Asterisk server available.

What you're probably more interested in is getting modules as Debian
packages where possible. Where they exist, they are normally called
something like libnet-dns-nameserver-perl (not a real Debian package,
by the way), adding 'lib' at the beginning, '-perl' at the end and
replacing the doubled colons with hyphens, all lower case. If that isn't
exactly right, a search should find what you want.

But there's a *lot* of perl... and only a subset is packaged in Debian.

Comment émettre des courriels d'alerte depuis des sites distants ?

Bonjour,

Je gère des serveurs sous Debian sur de multiples sites.
Ceux-ci sont configurés pour utiliser un compte Gmail quand ils émettent un
courriel (alerte, envoi fichiers).
J'utilise un compte unique pour des dizaines de machine.

Souvent, celles-ci n'émettent aucun message pendant des mois.

Quand elles en émettent, j'observe qu'il arrive souvent que ces messages
soient bloqués et que je reçoive à la place de Google, une alerte de
sécurité.

J'ai lu dans [1] que plutôt que configurer mes serveurs avec le login-mot
de passe du compte Gmail, il fallait utiliser un "mot de passe
d'application".

You mean those double colons ('::')?

If yes: those are just separators for the Perl module namespace, which
conceptually is a hierarchy. At the (right) end you can put some object
(function, variable) living in that module's [1] namespace.

Those are just a device to subdivide the namespace and to organize
file system "places" [1] -- they have no intrinsic "meaning" to perl
(i.e. the language itself has no notion of "Net" or "Net::DNS" -- just
of "Net::DNS::Nameserver").

Cf "perldoc -f require" for the full thing :-)

[1] In Perl parlance, it is a "package".
[2] Typically you'll find the package code in Net/DNS/Nameserver.pm

Quoting Richard Owlett (2019-04-24 19:36:29)

I'm attempting a very minimal install because:
1. small size in and of itself is a good goal
2. fending for oneself is a valuable educational experience compared
 to having everything handed to you on a "golden platter" {Debian's
 default installer}

My current experiments revolve around defining my personal take on a
minimal MATE desktop. Part of the motivation is that some recommended
packages clash with ones I wish to use. Just removing offending packages
after the fact is unaesthetic.

My test machine has both a default install from DVD 1 and my minimalist
install. I had done a standard install without specifying any GUI or
extra packages.

My base setup was installed by doing
apt-get --no-install-recommends install task-mate-desktop
apt-get install pluma gparted synaptic


I share your interest in installing minimal systems without the deroute
of first installing too much and then removing unwanted parts.

I understand from your subject that you deliberately chose to explore
first creating a broken system and then attempt to unbreak it.


It's not so much that I intentionally "broke" the system but I 
eliminated the "noise" of a set of sub-optimal permutation of recommends.


[One thing I've not sufficiently explored is the formal procedure/logic 
of recommending a particular package.]


The experiment met a preliminary goal. Using only *depends* does yield a 
"working", if not "productive",  system. Rather than being a "broken" 
system, I think of what I have as a "skeleton" that needs "flesh".




For the record, there's another (at least to me) more sensible approach
of explicitly skipping packages you don't want - e.g. like this:

   apt-get install task-mate-desktop libreoffice- libreoffice-gtk3-


I just re-read the apt-get man page. I assume that is applying:

If a hyphen is appended to the package name (with no intervening
space), the identified package will be removed if it is installed.

All it lacks is internet connectivity.


Unless you examined _every_ ignored recommendation and confirmed that
indeed you did not need it, you must mean "...known so far"!


 That meant only that  the lack of internet connectivity 
was preventing me from my planned activities. That lack was due to an error.

Antes de mais nada, sinto muito pelo seu imbróglio. É por isso que
normalmente nesses casos se faz o upgrade um release por vez! Claro, isso não
ajuda na sua situação atual, mas fica o aprendizado para a próxima ocasião.

Quanto ao seu problema atual, acho que ainda é possível recuperar sua
instalação.

Pela imagem que você mandou em anexo, você está tentando dar o boot com
o kernel 3.2.0, que entra em pânico aparentemente porque não está encontrando a
liblz4.so.1 (que deveria estar em /usr/lib/x86_64-linux-gnu/liblz4.so.1), que
normalmente é um link para o arquivo real, que pode ter sido substituído no
upgrade, e por algum motivo o kernel não consegue carregar (infelizmente a
imagem cortou a mensagem, então não dá pra ter certeza de qual o erro).

Nesse caso, você pode montar o seu raiz no /mnt, e montar as outras
relativamente a ele. Então o /boot ficaria em /mnt/boot, e assim por diante.

Naturalmente isso vai falhar, já que o seu sistema não faz idéia do que
fazer com esse kernel 4.9. Digo, o kernel se sustena por si próprio, mas não
necessariamente o seu sistema vai saber conversar com ele. Bibliotecas
importantes como a libc, por exemplo, receberam vários upgrades desde a Squeeze
e não serão, necessariamente, compatíveis. 

A pergunta é: você ainda tem o kernel 2.6 da Squeeze instalado? Se sim,
tente iniciar por ele, acho que seria a melhor chance.
Acredito que, se existe chance de recuperar esse sistema, será se esse
kernel conseguir dar o boot sem pânico. 

SUPONDO que você consiga esse boot, o próximo passo é recuperar a sua
instalação da Squeeze. Para fazer isso, faça o seguinte:

1) Remova todas as linhas do seu sources.list que não sejam da Squeeze. 

2) Edite o arquivo /etc/apt/preferences, e adicione o seguinte:

Package: *
Pin: release n=squeeze
Pin-Priority: 1001

3) Verifique se o diretório /etc/apt/preferences.d (se existir) não contém
nenhum outro arquivo que possa entrar em conflito com esse (na dúvida, remova os
arquivos e coloque de volta depois)

4) Faça a sequência normal de upgrade:

# apt update
# apt upgrade
# apt dist-upgrade

Supondo que isso corra bem, ao final do processo você deverá ter de volta a sua
instalação da Squeeze. Remova a configuração do /etc/apt/preferences, e faça os
upgrades em sequência - com paciência, de release em release.

Espero que isto ajude.


Abraços
Francisco

You mean those double colons ('::')?

If yes: those are just separators for the Perl module namespace, which
conceptually is a hierarchy. At the (right) end you can put some object
(function, variable) living in that module's [1] namespace.

Those are just a device to subdivide the namespace and to organize
file system "places" [1] -- they have no intrinsic "meaning" to perl
(i.e. the language itself has no notion of "Net" or "Net::DNS" -- just
of "Net::DNS::Nameserver").

Cf "perldoc -f require" for the full thing :-)

Cheers

[1] In Perl parlance, it is a "package".
[2] Typically you'll find the package code in Net/DNS/Nameserver.pm
   under a suitable "module root", e.g. /usr/share/perl5. The whole
   list of roots is in the special array variable @INC.

It usually translates to directory separators (/).  In your case, it
points to

/usr/share/perl5/Net/DNS/Nameserver.pm


Ah OK, I thought it might be some new scheme of things.

I share your interest in installing minimal systems without the deroute 
of first installing too much and then removing unwanted parts.

I understand from your subject that you deliberately chose to explore 
first creating a broken system and then attempt to unbreak it.

For the record, there's another (at least to me) more sensible approach 
of explicitly skipping packages you don't want - e.g. like this:

  apt-get install task-mate-desktop libreoffice- libreoffice-gtk3-

Personally I use aptitude in fullscreen mode (i.e. run "aptitude" with 
no non-option arguments) to explore package relations (dependencies, 
recommendations, suggests, and enancements) interactively.

When I then have a set of explicit package selections possibly with 
explicit recommendation suppressions, I save those as classes for the 
tool "boxer" for reuse across many different larger system compositions.

Re: TeamSpeak 3 et variable d’environnement SSL_CERT_DIR ou SSL_CERT_FILE

Je ne connais pas TeamSpeak, mais le paquet ca-certificates me semble un
peu vieux. Sur mon système (Debian Buster), le numéro de version est
20190110. Ceci explique peut-être cela.

Pour en avoir le cœur net, il faudrait récupérer le certificat TLS/SSL
de TeamSpeak, regarder quelle autorité l'a généré et voir si ce
certificat de cette autorité est fourni par le paquet ca-certificates
20180409.

Sinon, tu peux aussi tenter de regénérer le fichier
/etc/ssl/certs/ca-certificates.crt via la commande :

sudo update-ca-certificates -f

TeamSpeak 3 et variable d’environnement SSL_CERT_DIR ou SSL_CERT_FILE

[JUPIN Alain]

Bonjour,

Bon je sais que cela va être un peu HS car il s'agit d'une problème sous
Ubuntu 18.04 LTS (mais basée sur Debian). N'ayant pu trouver de
solutions sur les forums dédiés à Ubuntu je tente ma chance ici !

J'ai depuis de nombreuses années TeamSpeak 3 d'installer sur ma machine
sans aucun soucis. Mais cette semaine, suite à sa mise à jour (de TS3
voire de l'OS lui-même), je n'arrive plus à démarrer ce dernier. J'ai le
message d'erreur suivant :

|Échec du chargement de certificats d’autorité de certification !
Veuillez installer des certificats d’autorité de certification sur votre
système ou indiquer l’emplacement en utilisant la variable
d’environnement SSL_CERT_DIR ou SSL_CERT_FILE.|

Pourtant, ca-certificates est bien installé dans sa dernière version,
donc à jour !

|$ sudo dpkg -l | grep ca-certificates ii ca-certificates 20180409 all
Common CA certificates ii ca-certificates-java 20180516ubuntu1~18.04.1
all Common CA certificates (JKS keystore) ii ca-certificates-mono
4.6.2.7+dfsg-1ubuntu1 all Common CA certificates (Mono keystore)|

Dans le script de lancement de TeamSpeak, j'ai rajouté les lignes
suivantes (juste au dessus du lancement de teamspeak)

|export SSL_CERT_DIR="/etc/ssl/certs/" export
SSL_CERT_FILE="/etc/ssl/certs/ca-certificates.crt"|

Cela ne résout pas le problème, j'ai tenté de faire la même manip dans
le terminal, puis lancer le script de lancement de TS3, idem toujours le
même message.
Idem en ne mettant qu'une l'une ou l'autre des deux lignes précédemment
citées.

Comme il me semblait que cela venait d'une mise à jour de TS3, j'ai donc
essayer une version plus vieille (3.2.3 mais aussi 3.1.6) et dans les
deux cas, je me retrouve avec le même problème que celui cité plus haut !

PS : J'ai bien vu cette discussion : [résolu] certificats pour
TeamSpeak3 sous Ubuntu (Xubuntu) 18.04 LTS
, mais la solution
apportée ne fonctionne pas chez moi  !

Merci à vous si certains ont des idées et désolé pour le HS
