Rebooted and tried updating again. Did not work.
Chose partial update this time and everything downloaded once more with 5.13.0.11 kernel and all processes completed. Rebooted and got the new look with dual desktops showing up.

[Paride Legovini (paride)]

Hello and thanks for this bug report. You mentioned you hit this problem from a fresh 21.10 install, however two things that caught my attention:

 - The package you are trying to install is for i386, for which there is no installation media for Impish. I guess you added i386 as a foreign architecture, but then your system doesn't count as a "fresh install" anymore :-)
 - libwind0-heimdal 7.7.0+dfsg-2build1 is currently in impish-proposed, so I guess you manually enabled -proposed. This is fine (thanks for testing!), but again your system doesn't really qualify as a "fresh install" in this case.

Could you please provide steps reproduce the problem from an actual fresh install? If this requires adding i386 and -proposed that's fine, however in order to verify this is actually a bug in Ubuntu and start working on it we need a more complete reproducer.

I'm marking this report as Incomplete for now; please change it back to New after commenting back and we'll look at it again. Thanks!

[Fred (eldmannen+launchpad)]

I had this issue too, it got solved by rebooting and running Software Update (update-manager).

[Iain Lane (laney)]

Yeah I'm getting this too on dist-upgrade, now that heimdal migrated to impish.

[Dimitri John Ledkov (xnox)]

Is this debhelper or binary-package-mangler bug then?

[Iain Lane (laney)]

It's probably a bug in pkgstripfiles, will confirm

[Dimitri John Ledkov (xnox)]

In i386 build log I see

Searching for duplicated docs in dependency libroken18-heimdal...
  symlinking changelog.Debian.gz in libwind0-heimdal to file in libroken18-heimdal

I don't see something similar in adm64.

As if the trimming of the changelog entries got done before doing symlinks, instead of after.

I would have hoped that all packages are processed and things got symlinked first, then trimmed, in the same way on every arch.

Lots of sadness.

[Alailson Barbosa Ribeiro (alailsonribeiro)]

Working on the problem, I got the idea to move the symlink to another name and so I tried "apt -f install" and the con worked. I perform these steps:

$ cd /usr/share/doc/libwind0-heimdal/
$ mv changelog.Debian.gz changelog.Debian.gz.old
$ apt -f install

This bug was fixed in the package heimdal - 7.7.0+dfsg-2ubuntu1

heimdal (7.7.0+dfsg-2ubuntu1) impish; urgency=medium

  * Disable lto, to regain dep on roken, otherwise dependencies on amd64
    are different to i386 resulting in different files on amd64 and
    i386. LP: #1934936
