Up-to-date amd64 Jammy installation.

% cat /etc/issue
Ubuntu 22.04.1 LTS \n \l

% dpkg --print-foreign-architectures
i386


% dpkg -l libc6

ii  libc6:amd64    2.35-0ubuntu3.1 amd64        GNU C Library: Shared libraries
in  libc6:i386     <none>          i386         (no description available)

As far as I could understand, following prevents libc6:i386 installation:

% sudo dpkg -i libc6_2.35-0ubuntu3.1_i386.deb
...
(Reading database ... 228990 files and directories currently installed.)
Preparing to unpack libc6_2.35-0ubuntu3.1_i386.deb ...
Unpacking libc6:i386 (2.35-0ubuntu3.1) ...
dpkg: error processing archive libc6_2.35-0ubuntu3.1_i386.deb (--install):
 trying to overwrite shared '/usr/share/doc/libc6/NEWS.Debian.gz', which is different from other instances of package libc6:i386
Processing triggers for libc-bin (2.35-0ubuntu3.1) ...
Errors were encountered while processing:
 libc6_2.35-0ubuntu3.1_i386.deb

Two questions:

  1. How do I revert in status of i386 package in dpkg? Having package half-installed makes system look untidy, that's quite sad;
  2. Is above a temporary bug in Ubuntu packaging? Do I submit a bug to Canonical? I don't want trying manual removal of offending NEWS.Debian file, as I don't want to risk system stability and who knows which further conflicts are there ...

As a PS, running ubuntu-bug libc6 eventually produces quite "funny" output:

% ubuntu-bug libc6

The problem cannot be reported:


This does not seem to be an official Ubuntu package.

Turned out, for some reason, my sources.list was missing jammy-updates section (it had both jammy and jammy-security sections).

After I've added

deb http://mirror/ubuntu/ jammy-updates main restricted

and similar entries for universe/multiverse, I was able to install libc6:i386 via basic apt-get update/install way.

  • I got hit by a similar bug, I was unable to apt install valgrind because of some unmet dependency in libc6:i386. I checked my sources-list, and indeed there was no jammy-updates section. After adding it, I was able to install valgrind without problems. Thanks so much!! I have no clue why it was missing the updates section in sources.list, this was a fresh install 22.04.1 LTS with some additional PPAs but not much more. – ferdymercury Nov 24 '22 at 22:49
