Title:
  package libc6:amd64 2.31-0ubuntu9.1 failed to install/upgrade: package
  libc6:amd64 2.31-0ubuntu9.1 cannot be configured because libc6:i386 is
  at a different version (2.27-3ubuntu1.3)

Status in glibc package in Ubuntu:
  Fix Released
Status in glibc source package in Focal:
  Fix Committed
Status in glibc source package in Groovy:
  Fix Committed

Bug description:
  [Impact]

  * libc6 configuration error is observed during release upgrade from
  Bionic to Focal.

  [Test Case]

  * Copy the fixed package to a PPA and set up using the PPA on the Bionic system.
  * Break perl:

  $ mv /usr/bin/perl /usr/bin/perl.bak

  * Try upgrade to the fixed glibc binary packages

  $ do-release-upgrade --allow-third-party
  ...

  * The not fixed libc6 will show this error:

  Checking init scripts...
  /var/lib/dpkg/tmp.ci/preinst: 435: /var/lib/dpkg/tmp.ci/preinst: db_version: not found
  dpkg: error processing archive /tmp/apt-dpkg-install-rAF9HC/3-libc6_2.31-0ubuntu9.1_i386.deb (--unpack):
   new libc6:i386 package pre-installation script subprocess returned error exit status 127
  Selecting previously unselected package libcrypt1:i386.

  * With the fixed libc6 this error is not shown, maybe a different
  error shows up later due to broken perl.

  [Where problems could occur]

  * The fix is testing for the debconf interface properly, like it is
  done at many other places in preinst. It is unlike to cause problems,
  also the affected line is rarely executed.
