Note that it’s also possible to configure apt_preferences(5)
to avoid installation of unwanted packages (regardless of them
being recommended.) E. g. (though in this case it’s likely
libgl1-mesa-dri that rather should be avoided, see below):
$ cat < /etc/apt/preferences.d/55-no-x11-utils.pref
Explanation: The x11-utils package is not welcome on this system.
Package:
x11-utils
Pin: release c=main
Pin-Priority: -42
$
[…]
What’s going on here is that x11-utils contains, among others,
the /usr/bin/xdriinfo program, which is linked against libGL.
As such, the binary package automatically gets Depends: libgl1,
which is in turn dependent on libglx0 ← libglx-mesa0 ←
libgl1-mesa-dri, the last of which is itself large enough, and
also brings in a whole world of dependencies, as I’ve noted
in http://bugs.debian.org/960133 .
There’re several ways to resolve the issue, one of which is
indeed to move luit into a package of its own, though I can’t
say I’m particularly fond of practices that lead to the
expansion of the Packages files, as well as /var/lib/dpkg/.
FWIW, I haven’t noticed any ill effects due to the workaround
described in #960133 on Buster, but haven’t yet tested it
on Bullseye. Given that DRI modules are more often than not
useless without appropriate proprietary GPU software,
downgrading dependency on libgl1-mesa-dri to Recommends:
makes every sense to me.
Perhaps we should try to find and merge all such bugs together
and record ‘affects’ accordingly, to give the issue a tad more
attention and better cooperation / coordination? Thoughts?
