Thanks for all the details. It's great that your system is now fixed. Do
you have an idea why libc6 2.34 ended up in /usr/lib/x86_64-linux-gnu?
I do not see any explanation from the glibc side. Did you attempt a
usrmerge migration that failed after moving some files, or do you think
it's unrelated?
