[Bug 1871240] Re: [focal][wsl] can't upgrade from eoan to focal due to libc6 postinst

[Dimitri John Ledkov]

sleep: cannot read realtime clock: Invalid argument

Please escalate to WSL upstream, as the Windows kernel is not providing
the kernel interface that is needed to run focal.

In practice this means that focal is not yet supported on wsl1.

I expect things to work in wsl2.

  When trying to upgrade from Eoan to Focal in a WSL1 environment I got:

  And I could only mitigate that by editing:

  /var/lib/dpkg/info/libc6\:amd64.postinst

  and commented the line

  # set -e

  so $ apt-get -f install

  could continue.

  That happens because wsl does not have ubuntu kernel and directory
  structure is different.
