[Bug 1576960] Re: apt-mark prints ambiguous package name

The names aren't ambiguous – if apt prints no architecture it is ALWAYS
the native architecture. This is this way for compatibility reasons as
apt hadn't previously printed any architecture – because they were all
native – so old tools, scripts, processes, … sticking to the common case
of single-architecture systems do not need to be touched/fixed.

It just happens to be a different convention than dpkg is using – which
prints the architecture only if it could be ambiguous, like for all
packages marked as M-A:same (Since recently it also shows the
architecture for M-A:foreign packages of a non-native architecture, too)
and in exchange requires an architecture to be given (for M-A:same) even
if it isn't ambiguous [which broke pre-multiarch tools, but most tools
interacting with dpkg do this via apt which shielded them].

APT can't operate with this convention as basically every package is
available in all architectures, so a package name is always ambiguous
and hence all package names would need to be fully arch-qualified all
the time. That would be a lot of noise…
