I thought you had uninstalled cups-browsed from the bullseye machines.
Are the printers that you can't see actually on the network, or are
they connected to a specific machine (I didn't understand their being
"shared"). It was worrying that you said that one machine worked when
using the IP address but not its FQDN. (Actually, I've always thought
it misguided that that host, coyote, has the same name as the network.)

This support page discusses behavior for local folders. This thread is 
dedicated to specific of Gmail and Evolution interaction in respect to 
IMAP protocols. I mentioned compacting of folders in Thnderbird because 
earlier I have seen that performing "Compact" in Thunderbird expunges 
messages earlier marked for deletion. Strike through in message list may 
be a sign that the message is marked for deletion.


I expect that the following applies to message state on server, not to 
local folders:

RFC 3501 IMAPv4
2.3.2.  Flags Message Attribute


\Deleted
   Message is "deleted" for removal by later EXPUNGE


It is independent of maildir or mbox storage format of local folders or 
local offline cache of remote folder. Gmail may use internally some 
proprietary format that is neither mbox nor maildir, e.g. records in 
some database.


I like that Thunderbird exposes the "compact" option to UI because I 
earlier used it to forced removal of large messages from server account 
with rather strict quota. Several times I used "undelete" to recover 
messages I deleted by mistake, so I like that messages just marked for 
deletion by default as well.


The following is related neither to Evolution (at least directly) nor to 
Thunderbird, but still might be relevant:

https://support.microsoft.com/en-us/office/restore-deleted-messages-when-using-an-imap-account-4559a297-4d46-47e7-bfbf-71287b1935ed


If you use Google Gmail as an IMAP account, messages marked for deletion
are permanently deleted from their original folder but may still appear
there in strikethrough text. These messages are still recoverable
because a copy is kept in the Gmail Trash folder.

These statements may be confusing in the context of this thread. It is 
true that the action does not deletes messages if the user earlier has 
not requested removal. However in some cases it possible to undelete 
message before compacting, but not after. So it really deletes messages, 
perhaps hidden from UI (or displayed as strike through and still available).

The easy way to avoid that problem is to use LABEL rather than
(PART)UUID, because any time after the partitioner has run, while
it's installing more of the system, you can reset the LABEL back
to how you had it.

  # /target/sbin/swaplabel -L whatever /dev/sdXn

You can set the LABEL for the new system at leisure, because the
UUID that the installer used will still be working.

(I parenthesised (PART)UUID because I thought the installer set
and used UUIDs, not PARTUUIDs; but honestly, I might not notice if
any PARTUUIDs got reset: I only use LABELs and PARTLABELs myself.)

I can install bullseye and bookworm-RC1 standard software (no DE) on
an i386 laptop with ½GB memory using no swap, so that surprises me.

I presume your setupp (with VMs etc) is much more complex that my own,
so I can't understand why the booting process of one partition would
be affected by not identifying a different system on the same machine…

Yes, sorry, I don't use DEs. You might be able to find discussions
in the past list archives  about what's installed when you select
Debian desktop environment   without any DE from the list below.

That sounds as if you're harking back to the days when part two of
installation was running dselect after a reboot. That was tedious.
Since etch, it's been very much more straightforward.

I think you might have to explain more about the overall configuration
of your systems: I find it difficult to see how these booting
processes interact with one another. I have PCs with up to three
systems on them (buster/bullseye/bookworm), sharing /home and swap
(and obviously ESP), but they depend on each other beyond the fact
that each will mount the others' root filesystems (readonly) as a
convenience.

No fool like an old fool (debian installation probs)

[DdB]

Hello list,

after receiving so much good advice, i finally made up my mind and began
playing through the installation (debian bullseye, current stable) in my
simulation-VM in order to learn about the pitfalls to avoid. After more
than a dozen tries, i am running out of fuel, because i am continuously
running into problems, that i would have preferred to circumvent.

At first, i picked a debian (debian-11.6.0-amd64-DVD-1.iso), as the 11.7
release was not yet out), and installed from there, choosing the Expert
Install. The main reason was, that i was expecting to be invited into
customizing the system picking software to install by hand.

But at first, i ran into a multitude of problems with the partitioning
tool, even though the system was already properly configured (GPT +
EFISYS + OS + Swap + several other partitions booting in UEFI style).

For example, when i allow the use of the swap partition, it gets
reformatted and another PARTUUID is assigned to it, leading to failures
booting other systems from that disk. OTOH Disallowing its use for the
time being leads to install failures due to the 4GB of RAM apparently
not being enough for that VM.

Another problem, similar but distinctly different happens around the OS
partition. Whenever i gave it to the installer, it reformatted it while
changing the PARTUUID, again leading to failures in the boot process of
the other partitions... Until i discovered this workaround: Assign the
partition to ext4 and the mountpoint / but not allowing to delete its
content (as that would induce the reformatting). Instead, after
finishing partitioning, i asked for a shell and from there manually
deleted ONLY THE DATA from the partition(s) used. Then installation
progressed further.

BTW: Apparently, this was the only way to keep the PARTUUID, as deleting
the data by overwriting with zeroes lead to the installer overwriting
the fs structures making another mke2fs necessary.

But the worst of all, was the software selection: Even though i asked
for debconf priority low, i got only a few checkboxes to pick from. And
choosing GNOME did automatically install software i neither need nor want.

But omitting GNOME from the list lead to a system failing to boot with
tons of messages stating the absense of all kind of gnome parts.

So, just in order to make some progress, i had to willingly and
temporarily kill the bootability of other partitions in order to have
the install terminate without failures.

At that point, i decided to try the netinstall, as it is now available
with release 11.7 and i did expect there to be more choices. And when
even that one failed to boot without GNOME, i even did check the
sha512sum to make sure, i was using the proper one. - I did!

Now, i am confused. Many years ago, the expert installer was very
difficult to use and did provide very many choices (and liberties to
spoil the fun). Now, i dont seem to be able at coming to the stage,
where i can seriously test more complicated things (like multi-boot,
zfs, and other things) that make up my current host in its buster version.

It is quite obvious, that i am lacking SOME kind of understanding,
because what i am trying to accomplish should really be quite easy, but
i am only experiencing troubles.

Oh, as a side note: As a nicety of my setup, i can use bash scripts,
that work well from my main OS, or from the simulation VM which can be
used to test functionality before it is rolled out to the host. That is
why, i am relying/insisting on absolutely identical PARTUUIDs inside
that VM.

Now, i am really curious as to how to get to a proper system without
having to go through the baby-steps beginning with debootstrap, and all
the millions of configuration steps, that i did not even bother to list.

I am really interested to understand, in which way i am creating all
those problems for myself. Could it be related to the fact, that i am
accessing the net fom a VPN? - I don't think so.

Any suggestions/questions/hints from the power-users in here?
... would be wildly appreciated ...

Take a look at
  https://wiki.debian.org/CUPSQuickPrintQueues

The quick ref is to install avahi-utils and run
  avahi-browse -rt _ipp._tcp  | grep URF

If you get a line matching URF the printer supports the AirPrint
service.  Install cups and see if it works (which is all that I needed
to do to get the printer working).  If no, what does

  avahi-browse -rt _ipp._tcp

and

  systemctl status avahi-daemon

show you?

Hi, Tomas.  

Okay, it looks like Evolution does indeed use the MAILDIR format.  See:

https://help.gnome.org/users/evolution/stable/import-supported-file-formats.html.en

which says, 

"The format used by Evolution (for local folders since version 3.0).
There is no need to import Maildir files as you can configure a Maildir
account in Evolution and point to the folder where the Maildir files
are stored."  

And according to:

https://support.mozilla.org/en-US/kb/compacting-folders  


MBOX is the default format, where all of a folder's messages are stored
in a single file on disk. This is where the compact process is useful,
and the purpose of this article is to explain how and why.  

Maildir is a newer storage format, where every message of a folder is a
separate file. Maildir does not need compact, and so this article is
not applicable to Maildir folders. 

So, apparently Evolution does not need "compacting"!  

BTW, interesting that Thunderbird seems to still use the mbox format by
default, although you can apparently choose to store messages in either
mbox or maildir format.  Which is why they explain and offer the choice
to users.  

repeat of previous question that has gone unanswered several times.

[gene heskett]

Greetings all;

I have a mixed home network, some buster, some bullseye, all up to date 
a/o yesterday.


I have 2 printers shared on this bullseye main box, available as 5 or 6 
printers, each configured in cups to do a specific job. Good printers, 
both running on brother's own linux drivers for that printer.


All my buster machines can use both of these printers just as if they 
were plugged into that machine, but a machine shop full of sawdust and 
metal shavings is not a good printer environment, even if there was room 
for them, which there isn't.


All of my bullseye machines are locked out, printer screen at 
localhost:631 is empty, and no printers can be found and added.


But open a shell, and type "lpstat -t" and it gets the full list of 
available printers on that same bullseye machine whose cups output is empty.


Why?

Thank you for any insight.

Re: Segfaults after upgrade to Debian 11.7 on virtualized systems with AMD Ryzen CPU

Yes, seeing similar issue here, Deb 11 guest on AMD-based libvirt 
hypervisor, with vCPU configured as "EPYC-Rome".


The point at which segfaults occur seems slightly non-deterministic, 
rebooting the server into the same kernel crashes at different points. 
Sometimes the console dumps to initramfs debug, sometimes earlier.


Generally segfaults around LVM related calls, in libv-2.31.so as you are 
experiencing:


lvm[120]: segfault at 7ffc7d266c58 ip 7f64pd860f31 sp 
7ffc7d266c58 error 25 in libc-2.31.so[7f640d78e000+159000]

Code: Unable to access opcode bytes at RIP 0x7f640d860f07.

Sometimes loops a "Volume group "" not found" message, 
sometimes with an additional "sh: bad number" error.


Sometimes gets far enough into boot to fsck the LVM device, but then 
systemd starts erroring with failure to mount messages (I've seen 
"Failed to mount POSIX Message Queue File System", and "Failed to mount

Previous kernel 5.10.0-21 boots fine.

This basically explains that compacting is an operation that should
fundamentally be transparent to the user, and that Thunderbird makes the
user aware of it for ... no good reason.

Thunderbird will compact things for you as needed even if you don't
explicitly ask for it, so you don't need to worry about it.

Evolution doesn't bother the user with this, which is the better option.

Hi Tixy.

I don't know technically what "compacting" is supposed to mean, but
just as a total guess, I wonder if it is something like the 'vacuuming"
operation for databases. 

According to this:
https://support.mozilla.org/en-US/kb/compacting-folders
compacting does not:
- delete messages
- remove messages
- compress folders

Note that this just says that compacting improves performance.  But I
believe I have read elsewhere that not compacting regularly can have
potentially dire consequences, such as corrupted email storage files
and lost email messages.  

Also consider this:
https://thunderbirdtweaks.blogspot.com/2011/07/compacting-what-is-it-and-why-must-i-do.html

So "expunging" emails may not be the same thing as compacting.  FWIW,
in Evolution I had multiple email accounts with more than 1,000
messages each, including one which had over 24,000 messages!  Spending
many days, deleting sometimes several hundred messages at a time, I
have now reduced that to less than 6,000. No lost messages or file
corruption yet . . .

It does occur to me that Evolution may use the maildir format rather
than the mbox format.  I just ASSumed that it used mbox, since in Menu
> File, there is an option to save messages in mbox format.  If
Evolution uses the maildir format, compacting apparently does not
apply, which would seem to explain it.  I have not yet determined
whether Evolution uses mbox or maildir.  

BTW, I also never did really like the wastebasket (recycle bin)
concept, in any application program.  After all, delete should mean
delete, right?  But I must confess that the wastebasket idea has
rescued me more than once from a deletion by mistake, or when I have
"changed my mind"!

Hi, D.R.,

If I understand your question correctly, try this:

Click on the pane that shows the message contents, to select it. 
Then Ctrl + and Ctrl - let's you resize the contents of the pane,
bigger or smaller, respectively. 

Works on my Thunderbird, 102.10.0. 

HTH!

Thunderbird and font size used to display plain text e-mails?

[D. R. Evans]

I have looked everywhere I can think of, and have been unable to find an 
answer -- among the ridiculous number of ways that fonts appear to be 
controlled in Thunderbird -- that works for this issue :-(


I recently changed to a larger monitor, and, after lots of twiddling, have 
more-or-less got most programs looking reasonably sensible. But Thunderbird is 
being recalcitrant.


I am using TB 102.10.0, which is the current version in the debian stable 
repositories, on 64-bit debian stable.


Here is the issue:

When I open TB, I see three panes: one runs the full height of the TB window, 
and is on the left of the screen. It contains a list of the TB e-mail folders. 
The remaining space is divided into two panes, one vertically above the other. 
The second pane, the top one of these two, shows the subjects of received 
e-mails in whatever folder is selected in the first pane. The third pane, 
below the second one, is where the contents of e-mails are displayed.


I have TB configured so as to display incoming e-mail as plain text. They 
display correctly, BUT the font used to display the contents in the third pane 
is too large on the new monitor. How *exactly* do I control the size of the 
font used to display the contents of received plain text e-mails?


That is:

This is probably the intended meaning. For strange historical reasons
(mbox), reclaiming the space of a deleted mail used to be a non trivial
operation, so the user interface separated both: marking single mails
for deletion and actually doing it (which went by different names,
like "expunge", possibly "compact" -- the latter reminiscent of crushing
the holes left in a linear mbox).

That user interface proved useful for other reasons (time for remorse),
so it stuck, probably.

So yes, wastebasket emptying is probably it.

Interesting, but certainly not good.  On Stackoverflow you can find a
thread[1] how to interpret these segfault messages.

My first idea would be that the libc6 upgrade triggered these problems,
although the new kernel could also be at fault.  Try downgrading libc6
in one of the VMs to version 2.31-13+deb11u5 and see if that helps.

Good luck,
Sven

Hi!

A follow-up, because after reading my previous mail again I think
I should clarify one thing...

The Debian 11.7 VMs crash only when the system is booted with
the current Debian 11.7 kernel (5.10.0-22 i.e. Linux 5.10.178-3
from 2023-04-22) and initrd created when upgrading to 11.7.

When I select the previous entry in the boot menu (kernel 5.10.0-21,
Linux 5.10.162-1 from 2023-01-21 and initrd for this kernel) the
same system boots fine and is perfectly usable.

Any ideas anyone?

What is 'compacting', what is it meant to do? Sounds like 'compressing'
to me, don't know if protocols like IMAP has a way to ask the server to
compress it's folders. (I would have though how emails are actually
stored would be an internal implementation detail of the server).

If it just means really deleting email, then you can select the menu
option File > Empty Wastebasket which does that for all accounts. Or
for just a single account, right click on it's Wastebasket. There is
also Folder > Expunge which I believe does it for a single folder.

You can also configure Evolution to empty the wastebasket after a
period of time, or as I have it configured, whenever you close
Evolution. (I've always hated the idea of Wastebaskets, if I delete
something I want it deleted, not just hidden and taking up space).

Hi, Max.

I can not seem to find any information about compacting folders in
Evolution.  Which is strange. In Thunderbird, you can manually compact
folders any time, and it will compact automatically by default, with
adjustable parameters.  

Perhaps Evolution considers "expunging" (actual deletion) of messages
in the Trash folder, or otherwise marked for deletion (except in the
All Mail folder), as "compacting".  I sure hope that Evolution is
actually compacting folders somehow, and just not bothering to explain
when or how.  

Anyway, I think I have spent enough time on the Evolution All Mail
folder issue.  For now, I will just add one or more "Saved" folders,
and pretty much just ignore the All Mail folder, unless for some reason
I need to move messages from there to other folders. 

So, thanks to all who weighed in on the issue. 

(BTW, if anyone does have information about compacting folders in
Evolution, I would love to hear about it!)

Segfaults after upgrade to Debian 11.7 on virtualized systems with AMD Ryzen CPU

[Andreas Haumer]

Hi!

I have several virtualized systems around here.

Yesterday I upgraded some of our Bullseye VMs to 11.7 and found,
that now all systems running on a host with an AMD Ryzen 5950X CPU now
crash with segfaults at various commands.

I have other VMs running on a server with an AMD EPYC CPU.
Those VMs work fine with Debian 11.7

But the VMs on the AMD Ryzen 5950X host now all crash.

The kernel boots and I see the following messages (excerpt):

Fwd: Problème pour servir à un exécutable sa dépendance à libc.so.6 (debian 11)

[roger . tarani]

Je corrige : il s'agit plutôt du dynamic _linker_ (et non dynamic loader). 

Pour régler le problème décrit, il s'agirait peut-être de rendre disponible 
/lib64/ld-linux-x86-64.so. 
Qu'en pensez-vous ? 



Quant à linux-vdso.so (virtual symbolic link to the bitness-compatible ; vDSO =

Objet: Problème pour servir à un exécutable sa dépendance à libc.so.6 (debian

Bonjour, 

J'ai un problème pour faire fonctionner un programme (truc) qui a une 
dépendance à libc (à libc.so.6). 

Il fonctionne sans problème sur 6 hôtes debian11 sur lesquels je l'ai testé. 
Sans besoin d'utiliser LD_LIBRARY_PATH. 

Il ne fonctionne pas sur l'hôte debian11 configuré de zéro par un utilisateur 
peu coopératif qui attend que "ça marche tout seul" sans se poser de telles 
questions. 

Voici les dépendances de l'exécutable 
$ ldd truc 
linux-vdso.so.1 (0x7ffef8f73000) 
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x7f4f87607000) 
/lib64/ld-linux-x86-64.so.2 (0x7f4f87813000) 

L'hôte (Architecture : x86_64) et l'exécutable (En-tête ELF: Classe: ELF64) 
sont en 64 bits... 

Sur l'hôte qui pose problème : 
- libc.so.6 est bien présent. Et est donc inaccessible à l'exécutable. 
- la commande ldconfig est introuvable. J'attends de savoir si 
/usr/sbin/ldconfig existe. 

Sur un hôte qui sert correctement libc.so.6 au même exécutable, il y a les 
liens symboliques suivants vers ld-2.31.so 

lrwxrwxrwx 1 root root 32 Apr 19 23:17 /lib64/ld-linux-x86-64.so.2 ->

/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 -> ld-2.31.so 

Cela manque sur l'hôte qui pose problème. 

Je n'ai JAMAIS eu besoin de gérer cette dépendance occasionnelle du point de 
vue de l'utilisateur. 

Peut-être qu'installer gcc réglerait le problème ou utiliser un 'dpkg 
reconfigure' ou créer à la main un lien symbolique. 
Je crains de m'égarer en ne respectant pas la manière de faire ça sur un hôte 
debian (cad configurer et utiliser le dynamic loader, si j'ai bien compris). 

Comment traiter _propremement_ ce problème ? 

Merci.

liens symboliques suivants vers ld-2.31.so 

lrwxrwxrwx 1 root root 32 Apr 19 23:17 /lib64/ld-linux-x86-64.so.2 -> 
/lib/x86_64-linux-gnu/ld-2.31.so 

-rwxr-xr-x 1 root root 177928 Apr 19 23:17 /lib/x86_64-linux-gnu/ld-2.31.so 
lrwxrwxrwx 1 root root 10 Apr 19 23:17 
/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 -> ld-2.31.so 

Cela manque sur l'hôte qui pose problème. 

Je n'ai JAMAIS eu besoin de gérer cette dépendance occasionnelle du point de 
vue de l'utilisateur. 

Peut-être qu'installer gcc réglerait le problème ou utiliser un 'dpkg 
reconfigure' ou créer à la main un lien symbolique. 
Je crains de m'égarer en ne respectant pas la manière de faire ça sur un hôte 
debian (cad configurer et utiliser le dynamic loader, si j'ai bien compris). 

Comment traiter _propremement_ ce problème ? 

Merci.

The EPSON ET M1120 does not come with enough intelligence to be certified
as AirPrintint-capable. Therefore, it may or may not be be a driverless
device. The printer would need to be queried and its attributes examined
to make a decision.
