Package: calamares
Version: 3.3.0-1
Severity: serious
User: debian-...@lists.debian.org

Hi Jonathan,

Analysis of the archive for the 64-bit time_t transition[0][1] identifies
calamares as a package shipping a library whose ABI changes on 32-bit
architectures with 64-bit time_t.

However, calamares's shlibs file declares a dependency on a library package
name that contains no ABI information:

$ cat DEBIAN/shlibs
libcalamares 3.3 calamares (>= 3.3.0)
libcalamaresui 3.3 calamares (>= 3.3.0)
$

It is therefore not obvious that we should rename the package to
'calamares-t64' as part of this transition.

Looking at the archive, there are packages built from separate source
packages, 'calamares-extensions' and 'calamares-settings-mobian', which
depend on this library.

Since there is no self-evident thing to do with the library package name
here, we will not be handling this package as part of the mass NMUs. 
Instead I am filing a serious bug because partial upgrades from bookworm to
trixie on 32-bit architectures (upgrading calamares without also upgrading
worker) will result in ABI skew and may result in broken behavior.

However, since calamares is an installer, maybe upgrades are a non-issue and
all you need is to ensure rebuilds of the three packages in unstable.

Thanks,
