Ah yes.
I'm not sure you'll get much more from my system and logs now, can I
install systemd:amd64 back now ?

I have no idea how this happened either and why apt decided to replace
systemd:amd64 with systemd:i386 on an amd64 system.
But apparently you are not the only one,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=893054 sounds like the
user ran into a similar problem.

Do you still have the apt logs (check /var/log/apt) which show the
installation of systemd:i386 and removal of systemd:amd64?

Julian, do you have an idea why something like this can happen?

[LEDUQUE Mickaël]

Is it possible it could be because I put a package (I think it was a
systemd package) on hold because apt warned me about a critical bug on
systemd or udev about one week ago ?

Does that mean you have a udev:i386 installed on a amd64 system?



If so, that would basically be a duplicate of #869719

Ok, thanks.
Once you are dropped into the rescue shell, can you try running
systemd-udevd manually, via
/lib/systemd/systemd-udevd

If that works, you can try disabling the security features in
/lib/systemd/system/systemd-udevd.service
by commenting out the lines

MemoryDenyWriteExecute=yes
RestrictRealtime=yes
RestrictAddressFamilies=AF_UNIX AF_NETLINK AF_INET AF_INET6
SystemCallArchitectures=native
LockPersonality=yes

one by one and test if that makes a difference.

Ok, I was more searching for a way to do it from inside grub itself, but

I don't. But this is literally the first google hit regarding that question

See https://freedesktop.org/wiki/Software/systemd/Debugging/
"If You Can Get a Shell", and attach the journalctl output of such a boot.
Since this affects udev, please also consider adding
udev.log_priority=debug to the kernel command line (see man
kernel-command-line)

Bug#893369: systemd-udevd is killed at startup

[Mickaël Leduque]

Package: systemd
Version: 238-2
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After an update and a restart of the system, boot fails. It enters a loop, 
where (apparently) systemd-udevd fails to start and is retries for a certain 
time.
After thaat, I am dropped into recovery mode (or failsafe, I don't remember the 
word).
I tried investigating the logs, but I couldn't go very far, I just saw 
something that may (or may nt) be related, seccomp logs about systemd-udevd 
using a syscall
but that's an "audit" log so I'm not sure it does anyhting at all.
