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)

[Vadász Zoltán B.]

[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.

Status changed to 'Confirmed' because the bug affects multiple users.

[Balint Reczey (rbalint)]

While I see where this should be fixed in preinst I'm wondering how you performed the release upgrade to hit the issue.

[Launchpad Janitor (janitor)]

This bug was fixed in the package glibc - 2.32-0ubuntu5

---------------
glibc (2.32-0ubuntu5) hirsute; urgency=medium

  * debian/gbp.conf: Set debian-tag and debian-tag-msg to follow Ubuntu format
  * Don't build libc6-prof in stage1 and stage2
  * Ship libc6-prof on riscv64, too.
    This fixes FTBFS on riscv64 due to the the flavour being built but not
    shipped in a package.
  * Detect debconf consistently in libc6.preinst and do not crash if it is not used
    (LP: #1902955)
  * Prevent rare deadlock in pthread_cond_signal (LP: #1899800)
  * debian/patches/git-updates.diff: update from upstream stable branch

glibc (2.32-0ubuntu4) hirsute; urgency=medium

  * tests: XFAIL time/tst-cpuclock1 on armel, too. (LP: #1895687)
    The armhf build builds for armel, too, thus this fixes the armhf
    autopkgtest.
  * debian/control: Only recommend libnss-nis and libnss-nisplus.
    They pull in a sizable amount of extra dependencies while they are rarely
    needed.
  * Make libc6 provide libc6-lse on arm64.
    Libc6 is now compiled with -moutline-atomics thus the separate binary
    package is dropped.
  * Ship libc variant compiled for profiling in libc6-prof
  * debian/patches/git-updates.diff: update from upstream stable branch
  * Drop obsoleted local-cudacc-float128.diff which breaks new icc
    (LP: #1895358)
  * XFAIL tst-sysvshm-linux on i386 and x32
  * Merge 2.31-4 from Debian unstable

I could reproduce the issue by breaking perl before do-release-upgrade, but possibly there are other ways do trigger it.
