Yes, in the past, one goal was to have the source for both MPFR
versions 2.4 (mpfr) and 3.0 (mpfr4) at the same time in sid.
IIRC, this kind of things was common at that time.

This is related to the ABI versions, not API.

No. libmpfr4 3.1.6-1 was built from mpfr4 3.1.6-1 and
libmpfr6 4.0.1-1 was built from mpfr4 4.0.1-1.

The package names are different due to ABI incompatibility
between MPFR 3.1 (which implements interfaces 4 and 5) and
MPFR 4.0 (which implements interface 6).

Hello world,



As the Apache MPM (Multi-Processing Module) prefork no longer supports HTTP/2 
and having updated to 9.5 (breaking my fully working HTTP/2 server), i wonder 
what are the plan for HTTP/2 support.


Is it better to wait for a fix ?

If so, when ?


Is it better to forget MPM, witch i dont know how to do it ( yes, this is 
August and i am lazy )


switching to nginx might be an option, but again, i am lazy...

ADD6B7E2 is an encryption subkey.  As this is not used, it was revoked
later (in 2014).

Newer archive signing keys no longer have an encryption subkey

I've been investigating and I'm still puzzled.

The findings can be resumed:
a) If I boot the kernel with break=premount and then execute
/scripts/local-top/cryptroot: I need to enter the passphrase three times
as expected instead of two. Last one I see the prompt a bit different in
bold (probably comes from systemd?).

b) If I boot the kernel with the parameter "debug" and then I execute
journalctl I can see:
"""
ago 02 23:30:05 pinux systemd-cryptsetup[498]: Added key to keyring as 
604875905.
"""

And if I execute keyctl show:
root@pinux:~# keyctl show
Session Keyring
 935647640 --alswrv  0 65534  keyring: _uid_ses.0
 575581655 --alswrv  0 65534   \_ keyring: _uid.0
 604875905 --alswrv  0 0   \_ user: cryptsetup
root@pinux:~# 

If I wait a bit (more than 90 seconds was the default timeout?):
root@pinux:~# keyctl show
Session Keyring
 935647640 --alswrv  0 65534  keyring: _uid_ses.0
 575581655 --alswrv  0 65534   \_ keyring: _uid.0
root@pinux:~# 

But I thought that keyrings were only used by decrypt_keyctl in /etc/crypttab?
where is this added? My initrd doesn't have keyctl installed.

All of this might be a red herring...

Any more ideas please let me know,

Unless you have specialized needs it doesn't matter which of the MySQL
forks you use. WordPress only uses general MySQL functionality, so use
whatever's in the repo.

For debian there's now default-mysql-server which is a metapackage picking
up MariaDB.

The debian package will give you a sane install with MariaDB listening on
a socket and on localhost port 3306.

By default you can connect from a root shell by just typing "mysql".

Debian has some convenience stuff for upgrades and that moved from using
"debian-sys-maint˝ to using "root".

Read /usr/share/doc/mariadb-server-10.1/README.Debian.gz

You have now moved into an arena that the vast majority Debian users of

for issues which have been discussed numerous times in the past and for
which -user archives will provide you with an answer?

Apparently you are. My locale is GB.UTF-8. UTF makes me very happy. So
does GB. Your locale is something similar. You have no need of any other
locales. Just go with the flow.

You are either going to upgrade or not. Bloat doesn't come into it. The
packages to upgrade were useful to you before - why shouldn't they be
useful afterwards?

Your mail says - I upgraded Debian; it was completely successful.

Re: Kernel compilation problem

[Taren]

I did finally get the 4.17.11 kernel to compile so that my large drives 
are visible now, but I had to use a 'shotgun' approach in including as 
many SCSI/SATA/etc variables as possible.



I do intend on comparing the non-functioning config for 4.17.11 against 
both the functioning config, as well as against the config for 4.9.0-7-amd.

I'm running Stretch, with kernel 4.9.0.7, and am trying to compile a

The kernel builds successfully, but whenever I try booting into the
new kernel, I end up in emergency mode, with the error

 Unit dev-disk-by\x2duuid-.device has failed.

 The result is timeout.

This device is anmd device, with two mirrors (each 2.7T in size).
The submirrors are present when I boot into 4.9.0.7 (installed when
the system was built).
However, they do not appear to be visible under any kernel which I
build and try to boot into.

I've tried setting LBDAF in the kernel configuration, but that
requires that a 32bit kernel be built (and x64 deselected), and I'm
running on an AMD 8350 chip, which is x86_64.
Kernel 4.9.0.7 does not have LBDAF set (and x64 is set), yet it's
able to see my 2.7T drives, and my raid device mounts with no
problem.

I think this is a red herring. 32bit kernels need LBDAF for large
disks because they have to be told to use 64bit addressing for
them. Obviously 64bit kernels don't need telling, so that option
is made unavailable.


Would someone point me in the correct direction for configuring a
new kernel, so that my 2T+ drives are visible?

In the absence of other replies, I can only suggest
(a) comparing /boot/config-4.9.0-7-amd64 with the one you've
 built to see whether something is missing,
(b) compare the output of lsinitramfs /boot/initrd.img-4.9.0-7-amd64
 with the one you've built to see likewise.
I'm assuming with (b) that the disks have to be found by using the
initramfs before the system can continue booting with the filesystem
contained on those disks.

David.

It was a reaction by some of the MySQL original developers (Monty

leftovers, gained control of MySQL (MySQL had been sold to Sun before).

Obviously they didn't trust Oracle to be a good governor of a free

There isn't actually a big difference for the server whether it is
serving local clients or clients over the network. Authentication
is stricter for network clients (you can limit them by IP address
and so on), but that should be all.


Is there something focused on that topic. If it's explanation

As a first-timer, the best thing to do is let synaptic install
whatever it wants. Bloat will probably do you no harm.

As you gain experience, you'll be able to make your own judgments
as to what's really necessary, and then be a little more selective.
Again, as a greenhorn, you could just reinstall from scratch with
your new-found experience.

One idea that you might try is to have a drive partitioned with
several partitions, so that you can do these reinstalls on one
partition while leaving usable system(s) untouched until
you're happy with their successor.


The ONLY way to go :}
From Squeeze on, each of my installs have been made to a fresh 
partition. That was usually because I wanted to experiment with a 
different configuration.


Thanks.

What problem are you trying to solve?  https://wiki.debian.org/Synaptic
says synaptic is "targeted at ease of use" so maybe that is why it
does not have the helpful additional info you are looking for?


I suspected as much. I have a strange collection of background. I was 
introduced to programming with CORC/CUPL at Cornell in the early 60's. 
Dartmouth's BASIC later filled that market niche. In the 70's did some 
database management in dBaseII under close supervision. Later I did 
maintenance of 8085 assembler. I was never involved at the OS level 
until using Debian Squeeze.




On the other hand, each pkg can include scripts that run before or after
installation.  That may be why you were asked a question.  I think there
may be several ways to do it, but debconf https://wiki.debian.org/debconf
is probably the way it is handled for most pkgs?

Every pkg has a changelog, a debian changelog, sometime a NEWS.debian, and
usually one or two readme files at /usr/share/doc/ so maybe
looking up the readme for pkg locales will answer one of the questions.

good wiki here also https://wiki.debian.org/DebianPackageManagement



Next time I'll use command line tools. Looking up the man pages will 
help in deciding what path I wish to follow. Also, I suspect any 
questions will be at a more fine grained level.


I have bookmarked your links.

Thank you.

I think this is a red herring. 32bit kernels need LBDAF for large
disks because they have to be told to use 64bit addressing for
them. Obviously 64bit kernels don't need telling, so that option
is made unavailable.

> Would someone point me in the correct direction for configuring a

In the absence of other replies, I can only suggest
(a) comparing /boot/config-4.9.0-7-amd64 with the one you've
built to see whether something is missing,
(b) compare the output of lsinitramfs /boot/initrd.img-4.9.0-7-amd64
with the one you've built to see likewise.
I'm assuming with (b) that the disks have to be found by using the
initramfs before the system can continue booting with the filesystem
contained on those disks.

Cheers,
David.

You should instead be installing it from the usual debian-hosted
repositories, unless you have a known need for a specific release. The
usual repos normally have multiple releases of MariaDB/MySQL on them.

> It tries to be too many things for too many people

MariaDB/MySQL are today DBMS's of commercial depth and quality. That
wasn't always the case. One whole lot of Earth's commerce is riding on
them today. They are inherently complex and learning them takes time
and some background perhaps. Maybe Apache CouchDB would be better for
your purposes unless you expect scads of data.

It was a reaction by some of the MySQL original developers (Monty
Widenius among others) to the fact that Oracle, by buying Sun's
leftovers, gained control of MySQL (MySQL had been sold to Sun before).

Obviously they didn't trust Oracle to be a good governor of a free
competition to their crown jewel, and they forked MySQL (which is
possible, because it was under a free license). See [1].

There isn't actually a big difference for the server whether it is
serving local clients or clients over the network. Authentication
is stricter for network clients (you can limit them by IP address
and so on), but that should be all.

The problem is that there are *lots* of docs (it is a complex
topic, after all). You can start a long browsing excursion here

Shit happens. For relational databases there's a fine-grained access
control system. Typically you start by setting up a "root" user
(perhaps there is one and you only need to set up its credentials),
who can create databases and grant rights to the more pedestrian
users.

They do share much more. MariaDB is aimed at being a "drop in"
replacement for MySQL for those who want to keep Oracle at some
distance.

As it is a GUI ( not the command line ) I will not be able to use

It is likely that the kernel's idea of what is a "runnable" process
has changed since the vintage of the Red Hat kernel, compared to the
kernel which Debian stable uses.

The Debian kernel will be much closer to upstream. The RHEL kernel
will be much older with backports only of security issues and
serious bugs. Tweaking of load average stats probably did not make
the grade for a backport.

Here is some more information about how Linux load average is
calculated. This may help you to narrow down which processes are
being considered differently between the two kernels.

Because you're either (a) not running the 'ssh' command with enough

The message you posted a few mails ago - "DH Key exchange failed" - is

Given that port 22 is the standard port for SSH, I would be VERY
surprised that an ISP would get in the way of it.  I mean, sure, they
might've goofed - but if they were blocking it, you WOULD NOT be getting
far enough to have a diffie-hellman key exchange failure.  That's one of
the last parts of the handshake between an ssh server and ssh client ...

Well, since it seems you don't actually want help getting to the bottom
of the issue, good luck to you then.

The errors below seem to be hunting for "source" packages. Perhaps
you are missing an option to add apt sources for "source" packages?

(I haven't used multistrap sorry.)

Are these two lines part of the log, or did you add them to that log?


(Also, I recommend running an apt (or squid) proxy, so that you don't
 re-download packages unnecessarily.)


Good luck,

In my experience, major upgrades using aptitude sometimes get seriously
bogged down resolving dependencies, whereas apt-get and apt generally
run smoothly.

I also have found it generally works better to do apt-get upgrade
followed by apt-get dist-upgrade rather than trying to do it all in one
step, and that with rare exceptions, it all comes out right in the end,
although there occasionally are oopses that require a bit of additional
effort. If there are difference between apt-get and apt other than some
of the command names, I have not noticed them, and now generally use
apt.

Because it handles large numbers of simultaneous package upgrades
better.

Because it has more intelligent dependency handling, and will offer
various partial solutions when apt-get will just want to remove large
numbers of packages. When faced with hundreds of packages to sort out
dependencies for, aptitude can take a very long time to find an
answer, by which I mean hours rather than minutes.

It *is* efficient to have more than one alternative. It is not
efficient to have more than one *identical* alternative, and the
various Debian package tools are not identical. Should there be only
one web browser, only one email client, etc? Only one operating system?

I might do it another time - is that I'm more familiar (for when things
go wrong, and only because I have more experience) with usual partition
and not LVM and serve my purpose. As said, I might use LVM another time
:-)

I was asking "how to enter the passphrase only once" only to understand
why I'm entering it twice and not three times :-)

When I read it and also the initrd scripts I didn't understand why I
need to type it twice only when I was expecting three times... if I need
to read again some specific section let me know. I'll have another look
just in case.

Thanks for the other information! It might be handy at some point! :-)

Well, I thought "I might do a later day" and "I can test hibernation
this way". I'm fine entering the password 3 times if needed, I don't
restart that often at all I use suspend.

this is what I'd like to know: why I need to enter the passphrase twice
