[Bug 1926355] Re: Snap applications segfault with new core20 (rev: 1015+)

[Alkis Georgopoulos]

Hi, the libc update + removal caused the following issue:

1) On 2021-04-26, libc version 2.31-0ubuntu9.3 got uploaded to Ubuntu Focal.
2) Many people updated to it.
3) Two days later, on 2021-04-28, it got removed because it was causing the issues descripted in this bug report.
4) If any of the persons that updated, tries to install libc6-dev now, it says it's not installable as it depends on libc6=2.31-0ubuntu9.2, while 2.31-0ubuntu9.3 is installed.

In some cases they can downgrade with `apt install
libc6=2.31-0ubuntu9.2`, but that's not always easy when additional
dependencies are involved.

I believe a solution would be to re-upload 2.31-0ubuntu9.2 as
2.31-0ubuntu9.4. This would then not break snap, while allowing people
to install libc6-dev, as it wouldn't have a lower version than in the
archives anymore.

Bug description:
  It seems that with our new core20 in the beta channel all snaps seem
  to be segfaulting. We recently had a new glibc landed in focal-updates
  - might be related.
