Whatever caused systemd to want to be installed on my Stretch
system, but not on Buster or Sid when installing wicd which explicitly
states having no systemd dependency.

Someone traced that down.  Seems the systemd dependency is from a
Recommend or two for wicd. But this is all academic now.  I've decided
to abandoned wicd.  wifi-radar looked good and installed without a
hitch.

The install includes lots of choices like print server, server or
desktop system, GUI, laptop utilities, etc. that are "bloat-worthy" and
can be installed after the main install has completed.  I know.  I used
to do it back in the day. I still do to a certain extent even today.
But now those choices are an integral part of the install.  So, why not
init? Can't even spare a few hundred K? Ridiculous irrantionale. We're
talking CD/DVDs not floppies.

As far as what constitutes "essential": Shouldn't the user decide
that?  Or, at least, have a say so?  What has happened to the basic
philosophy of good business: Satisfy the customer?

I'm not against systemd, per se, just against having it forced on me
by way of dependencies. I don't think the init should ever be a
dependency. Of anything.  It's too basic to the system.

Didn't need scripts.  Debian already had the ability to switch to
sysvinit (probably because so many objected to systemd) by simply
installing sysvinit-core.  If it's that simple, why not make it part of
the install.  Yes, you won't be able to use GNOME, but freedom of choice
comes with consequences as do all choices.

One could do that, but a handy session of mc just 
copied /usr/share/gkrellm/* (which is where grabweather was installed by 
the deb pkg)to /usr/local/share/gkrellm/*
so I'll see if that fixes it shortly. Yes, it did, THANK YOU Ulf.

FWIW, I have not seen the error in the logs either. Who is supposed to 
own these files? And what perms are expected. 

Frankly, someones paranoia has made it impossible for anything I install 
to make and write to a log file in /var/log/ and I had to jump thru all 
sorts of perms loops to let even some of the stuff from the initial 
install actually keep logs. Its been such a pita that for stuff thats 
mine, I've moved the logs, and logrotates recipe's, to a log subdir in 
my home directory. Solves all them critters in one swell foop.  I would 
do that to gkrellm if it was a .conf option.  Everything I moved shows 
it belongs to root:root, but has enough perms, ahh, I see whatever 
starts and stops it is writeing to daemon.log. But not finding the 
weather plugin is never mentioned there. I don't believe anything that 
turn up in a grep -R query actually came from gkrellm.

But now its working, and I thank you very much.

tftp problem

[ghe]

buster, atftp, atftpd

atftpd writes to /srv/tftp, even when I change to /tftpboot in the
/etc/default config. Or, as is suggested in the man page, just leave
that part of the config empty. Restart doesn't impress it.

Nice piece of software, but I have to put a link in /srv to /tftpboot to
make it do what tftp is supposed to do. Anybody seen this? Or know how
to fix it?

Works fine, I just don't like it when I ask it to do something and I
have to create a little untidiness to make it happen...

Pues genial lo de la incidencia en Izenpe, ellos sabrán probar. De
todos modos se me ocurren dos posibles soluciones, que no creo que te
valgan ya que lo suyo es que la tarjeta de Izenpe funcione:

La primera es pedirle a Izenpe que te proporcione el par de claves en
un archivo (tipo certificado FNMT) y usar los certificados con el
dispositivo software del navegador. Desconozco como trabaja Izenpe, así
que no se si solo proporciona tarjetas físicas o también puede dar las
claves en un archivo. Probablemente no te guste porque quieras usar una
tarjeta física.

La segunda es comprar una tarjeta criptográfica estándar e instalar tu
mismo las claves en ella, y a partir de ahí ya no dependes del software
propietario de Izenpe ni del de nadie. Yo uso estas para llevar dentro
el certificado de la FNMT:

use mailx instead of sendmail in apt-listchanges

[Martin T]

Hi,

I have apt-listchanges installed and registered in apt system:

# apt-config dump | grep apt-listchanges
DPkg::Pre-Install-Pkgs:: "/usr/bin/apt-listchanges --apt || test $? -lt 10";
DPkg::Tools::Options::/usr/bin/apt-listchanges "";
DPkg::Tools::Options::/usr/bin/apt-listchanges::Version "2";
DPkg::Tools::Options::/usr/bin/apt-listchanges::InfoFD "20";
#

"frontend" in /etc/apt/listchanges.conf is set to "mail" and valid
e-mail address is set with "email_address" configuration option. Now
when I upgrade a package which has NEWS/changelog present, then I get
the "apt-listchanges: The mail frontend needs an installed 'sendmail',
using pager" error message. This is because I don't have
/usr/sbin/sendmail binary installed. I prefer to use mail/mailx and an
external MTA.

What could be the most elegant workaround in this situation? Create a
/usr/sbin/sendmail wrapper script which processes the
"/usr/sbin/sendmail -oi -t" command called by apt_listchanges.py and
sends the mail using mailx? Modify the apt_listchanges.py? Something
else?


thanks,
Martin

Put your modified configuration files and key data files into a version 
control system.  Validate.


Back up all configuration files and all data.  Validate.

Take an image of your system drive.

Disconnect all HDD's and/or SSD's.

Check motherboard firmware.  Update if necessary.

Install a new system drive.  Use the manufacturer's diagnostic tool to 
check the new system drive.  If it is okay, use the diagnostic to zero/ 
secure delete the drive.


Do a fresh install of your chosen OS.  Before rebooting the first time, 
shutdown and take an image of new system drive.


Update the operating system, if needed.

Check out your old configuration and data files into a working 
directory.  From this point forward, check in anything you create , 
update, delete.  Add anything you think might be important.


Reconnect data drive(s).

Install and/or set up one package at a time.  Merge your old 
configuration and data into the new layout.  Validate each item as you go.


Configure backups for new system.  Backup.  Validate.

Take image of system drive.

how to integrate ca-certificates with gpgsm (for email s/mime signature verification)

[Gregor Zattler]

Hi,

I use notmuch-emacs to read my email and sometimes do use GnuPG,
therefore notmuch-emacs is configured to verify signatures but
does so also for S/MIME  signatures.  When displaying such emails
I'm asked if I trust the respective Root CAs Cert.  That's tedious.

Therefore I would like to integrate certificates provided by
debians ca-certificates package with gpgsm, but the only way I
found to do so, would be to manually import all those
certificates.

Isn't there an option to read in those certs from /etc/ssl... at
start-up?

A resumé of parts of the first few messages in this thread might focus
minds. It started with

  > I edited sources.list to read
  >   deb file:///home/richard/dvd.iso stretch main contrib trusted=yes

It was pointed out by Dan Ritter (correctly) that 

  > The problem is that the .iso is not a mounted filesystem.

There is another mistake in the line which was regrettably perpetuated
by Dan when he gave the revised line

  > deb file:///home/richard/dvdmount stretch main contrib trusted=yes

On the OP saying

  > I now get a different error message:
  >   The repository 'file:/home/richard/dvdmount stretch Release' is not 
signed.

the advice was

  > Try [trusted=yes] and/or [allow-insecure=yes]

Hmm, an example line might have prevented the slide into apt mayhem.

At this point my guess would be that the OP substituted one malformed
line for another malformed line and sank deeper into the morass. A
rescue could be effected by using sources.lis(5) but there is, as yet,
no sign that its advice has been followed or tried.

Display.  (Don't recall make and model, but it was marketed as an
alternative to a separate Desktop and Tower).  My issue, was that the Video
Chip in the Docking Station was, enough different from the one, driving the
Laptop Screen to need, not only different Drivers, but different sections
in xorg.conf.

It worked for me to "Hot Plug" it into the Dock, and I could use both
monitors as separate Displays.  But I encountered something like your
symptom, if I "Hot Unplugged" it.  Something about Adding features being
okay, but taking them away giving "hilarious" Syslog Messages and, in my
case, only allowing access to it via ssh.

One diagnostic tool for me, was that lspci gave different results, in the
Dock and outside of it.

So I made a habit of shutting it down, before removing it from the Dock.

OpenGL forwarding via ssh session: works on jessie, does not work on stretch

[Simon S]

Hi,

I have a weird problem with opengl forwarding via ssh.
I am running debian jessie on my BeagleBone Black (armhf) that I use for my CNC 
machine by running machinekit.
Everything works as expected, I even got indirect opengl rendering working when 
I connect to the BBB using windows.

Now I tried to upgrade my setup using a more recent stretch based image.
I am not able to use opengl forwarding on stretch.

The following test setup:
(A) linux machine running ubuntu (Nvidia GPU)
(B) BBB running jessie
(C) BBB running stretch

I connect from (A) -> (*) by ssh -X x@host

When I connect from (A) to (B):
> export LIBGL_ALWAYS_INDIRECT=1;  glxinfo|head
name of display: localhost:10.0
display: localhost:10  screen: 0
direct rendering: No (LIBGL_ALWAYS_INDIRECT set)
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:

When I connect from (A) to (C):
> export LIBGL_ALWAYS_INDIRECT=1;  glxinfo|head
Error: couldn't find RGB GLX visual or fbconfig
name of display: localhost:10.0


Did something change from jessie -> stretch concerning x permissions?

Running plain x apps like xterm works in all cases.

I installed lxde on (c) and glxinfo/glxgears runs fine under lxde on the BBB.

Any hints?

This ia a viable alternative to get a line into sources.list and produce
the makings of a workable updating, upgrading and installing system.

Unfortunately, the OP will run into exactly the same problem(s) as he
would meet with file:///. . Solve those with the present URI type
and it is also solved for cdrom: .

The OP's declared motivation is "self-education" and what is wanted is
that it "should just work". By "it" I imagine he means using a d-i ISO
as a repository with the file URI type. Perhaps I didn't sufficiently
stress that he knows the basics, but, as suggested earlier, the
sources.list line is not constructed correctly. That is the first hurdle
and the sources.list manual is all that needs to be read to jump over it.

The second hurdle isn't that hard to stride over either.

My thinking went along the lines that a loop-mounted (if that is the
correct term) cd/dvd iso file is the effective equivalent of a cd/dvd in
the drive, in which case it appears apt-cdrom is the obligatory tool to
give APT what it requires to grok such an animal as a package repository.

One "trivial" method (though outside the strict delineations of the problem
space as you defined it) would be to mount the iso, create a directory ('mkdir 
-p
/var/lib/mydebs'), copy the debs from the iso to '/var/lib/mydebs', add 
'deb file:/var/lib/mydebs ./' to your sources.list, and run
'dpkg-scanpackages . | gzip > Packages.gz' in '/var/lib/mydebs'.

An 'apt-get update' from there and you should be ready to go (if we can
believe the wiki).

man apt-cdrom

It is necessary to use apt-cdrom to add CDs to the APT system; it cannot be
done by hand.  Furthermore each disc in a multi-CD set must be inserted and
scanned separately to account for possible mis-burns.

  /home/richard/dvdmount /mnt/dvdmount iso9660 user,loop 0 0

I intend to experiment with modifying files in /etc/apt/apt.conf.d
rather than modifying sources.list. This will require I dedicate a
separate machine to the experiment. I will also use that machine to
compare stretch to earlier releases.


If you have multiple machines, then there's a method I haven't seen
mentioned, which might be worth a try. It doesn't require any unusual
configuration parameters.

Install apt-cacher-ng on one of the systems, then copy all the .debs
into /var/cache/apt-cacher-ng/_import and let it place them all into
a repository. You control the package by pointing your browser at
http://localhost:3142/acng-report.html on the caching machine, and
use the cache by inserting into /etc/apt/apt.conf a line like
Acquire::http::Proxy "http://192.168.1.NNN:3142/;
depending on your network configuration.



For idiosyncratic reasons I do not have a network.
However, when I purchased the second machine, it was with the intention 
of occasionally erasing the disk for new experiments. IIRC a single 
machine can physically have both a server and a client. More reading to do.


You addresses a related issue, download bandwidth.
My current project is explicitly focused on using installation DVDs, or 
preferably their ISO images, as a 'repository'.


Why that is my goal is long and involved.
Part of my motivation is self-education.
What I want "should just work" 
"Why doesn't it?" is my current assignment {essay}.

Docking station with thinkpad T480s

[Thorsten]

Hi,
the docking station work well except one situation. If I get my laptop 
FROM the docking station, the screen is black. System work well, with 
ALT-F1 the console work. But the X-Server don't refresh the screen.


Any ideas?

Problem with Mate in Buster on T480s

[Thorsten]

Hi,
my desktop is mate on a Thinkpad T480s. Under preferences 
system->preferences->view->Window you can activate "Programmkomposit der 
Fensterverwaltung aktivieren" in english "Activate program composite 
window management". You can get a preview of your windows with key 
ALT-TAB.


If I activate this, the preview is OK. But the X-Server create a lot of 
errors per second like this:


[237861.491] (EE) modeset(0): Failed to get GBM bo for flip to new 
front.

[237861.491] (EE) modeset(0): present flip failed

It could be a bug. But how I proceed? Where is the bug, or how can I 
configure that right?

Merci,

En fait j'avais trouver sur G**gle que l'on pouvait ajouter le user à 
l'emplacement où j'ai mis la variable XDG_RUNTIME_DIR. Mais là ça ne marchait 
pas. J'aurai pensé qu'en mettant le user, cron aurait chargé l'ensemble des 
variables d'environnement de l'user mentionné.

Je ne suis pas sûr d'avoir compris la question mais cron a tendance à

Si tu lances cette même commande (env > /tmp/env.log) dans un script lancé

J'imagine que XDG_RUNTIME_DIR était bien définie dans un shell interactif
mais pas dans le contexte d'une exécution via cron.
