Thanks for your investigation. There is a buster running as a base system. I didn't notice that the libcrypt1 does not come from buster earlier. This situation is probably caused by newer openafs-client/bullseye package, which depends on libcrypt1/bullseye, which definitely breaks libc6/buster. There were several bugs in the openafs some time ago, so the decision was made to switch to the bullseye version, ending with weird distribution state. Removing the libcrypt1 package resolves the the problem. Cheers, Jan On Mon, 6 May 2024 20:00:10 +0300 Adrian Bunk <bunk@debian.org> wrote: > On Mon, May 06, 2024 at 05:37:37PM +0100, Adam D.
