[Bug 1926918] Re: cannot install libc6-dev, requires old libc6 version

[Martin Ritter]

I have to ask: Why wasn't the update reverted and not just withdrawn?

Especially if it causes regressions I would have assumed that there is
something like `2.31-0ubuntu9.3+really9.2` to be pushed into updates to
allow for smooth transitions out of the broken version.

Title:
  cannot install libc6-dev, requires old libc6 version

Status in glibc package in Ubuntu:
  In Progress

Bug description:
  Current version of libc6:amd64 in Focal is 2.31-0ubuntu9.3. libc6-dev
  requires 2.31-0ubuntu9.2 **only**. This prevents installation of
  libc6-dev (as originally discovered while trying to install build-
  essential, which also requires libc6-dev).
