Thanks for the log. Would it be possible to share the initial part
without errors? It seems the problem is not in the content of the
packages, but in the sequence of installation, so it would be useful to
know what got unpack and what didn't.
Just two random things to test to try to unbrick the system:
- Try running 'ldconfig'. As it seems that some postinst scripts have
been able to run before things start to crash, it could be that it is
not run properly.
- Try unsetting LC_ALL (and possibly LC_*) and LANGUAGES environment
variables. Given the issue appears in the tolower function, it could
be a problem with the locales.

This looks very strange that downgrading and re-upgrading fixes the
issue. Did the initial upgrade finished properly? You might want to look
for issues in /var/log/dpkg.log or /var/log/apt/term.log.

It should not matter how the upgrade is performed, and in any case
doesn't explain why your tests on tty2 and tty3 are also affected.

Bug#1040452: libc6: upgrading libc6 to version 2.37-3 break almost every program (especially in a shell)
Package: libc6 Version: 2.37-3 Severity: important Dear maintainers, I've just upgraded to libc6 2.37-3 and now I have an almost broken system. But broken in a very weird way: the graphical user interface (KDE Plasma) is coming up, I can start big programs like Firefox, Thunderbird, etc., but as soon as I go to a shell — it doesn't matter if I'm inside or outside the graphical session, ie. tty2 vs. tty3 — I can execute almost no program. ldd works, surprisingly gdb works as well, but eg. man or apt-get or perl do not. They all end with $ man apt-get Segmentation fault (core dumped) Since gdb is working, I got a backtrace, even though that is not that helpful, I fear. $ gdb --args man apt-get GNU gdb (Debian 13.2-1) 13.2 [...] Reading symbols from man...

The KDE session is also incomplete, eg. audio devices are no longer found. During the update I saw errors towards the end (post-install scripts) for libc6 (and some others, which should not matter here). Ie. the post-install script could not be executed with the core dumped/segmentation fault. It also doesn't matter what shell I use, I've tried bash and dash. This might be related to #1040140 reportbug is not working either, so you have to do without the automatically generated system information, but I do try to reproduce it here as close as I can. Now I will try to downgrade my system and get it fully functional again.
