Another variant of the problem that I mentioned in comment #15. An ubuntu user just reported it on IRC:
$ apt install clang The following packages have unmet dependencies: clang : Depends: clang-10 (>= 10~) but it is not going to be installed That apt message is misleading, as the underlying error is the libc6 version: $ dpkg -l | awk '$3=="2.31-0ubuntu9.3" { print $2, $3 }' libc-bin 2.31-0ubuntu9.3 libc-dev-bin 2.31-0ubuntu9.3 libc6:amd64 2.31-0ubuntu9.3 libc6:i386 2.31-0ubuntu9.3 libc6-dbg:amd64 2.31-0ubuntu9.3 libc6-dev:amd64 2.31-0ubuntu9.3 locales 2.31-0ubuntu9.3 To be able to install clang, all these packages would have to be downgraded manually, with: $ sudo apt install $(dpkg -l | awk '$3=="2.31-0ubuntu9.3" { print $2"=2.31-0ubuntu9.2" }') The following packages will be DOWNGRADED: libc-bin libc-dev-bin libc6 libc6:i386 libc6-dbg libc6-dev locales But we can't expect thousands of Ubuntu users to run that command manually. Please do upload a new glibc 2.31-0ubuntu9.4 version, to amend this issue... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926355 Title: Snap applications segfault with new core20 (rev: 1015+) To manage notifications about this bug go to: https://bugs.launchpad.net/snap-core20/+bug/1926355/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
