Package: libpam0g
Version: 1.4.0-9
Severity: important
Dear Maintainer,
While upgrading a Raspberry Pi from Buster to Bullseye, the postinst of
the libpam0g package failed, which resulted in a system in a
half-upgraded state. This could not be resolved by 'apt -fix-broken
install' because this would trigger the same bug again.
The bug in question is in debian/libpam0g.postinst, line 63:
failed = "$failed $1"
This should read:
failed="$failed $1"
I managed to repair my install by applying the fix above to
/var/lib/dpkg/info/libpam0g:armhf.postinst and then completed the upgrade.
The bug doesn't always get triggered, as an upgrade on another RPi did
not trigger it. Having the exim4 package installed may be a contributing
factor, because the code got triggered on trying to restart exim4.
Although I've encounted the bug on a Raspbian system, I've verified that
it is also present in the source package as shipped by Debian.
The VCS repository for this package unfortunately is at
1.4.0-1, while 1.4.0-9 is shipped with Bullseye. Could you please update
the repository in question?
Regards, Paul Boven.
