In the case where apt refuses to install and holds back certain
packages, only the following output is produced:
root@system:/home/admin# apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
[ List of packages ]
0 upgraded, 0 newly installed, 0 to remove and 24 not upgraded.
Missing is any explanation about which package is responsible for apt refusing
to perform its job, or even what is the reason for that package being
uninstallable.
This bug leads users to believe that official Ubuntu packages are
routinely misconstructed, corrupt, or otherwise junk.
Fix: Instead of apt simply responding "No Dave, I'm Afraid I Can't Do
that", correct the output to include the specific package that has a
missing or unresolved dependency, so the user a) has confidence that the
process works correctly and b) can proceed with fixing the problem.
This bug is longstanding, so I don't think version details are required, but
they follow anyway:
1) Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
2) # apt --version
apt 2.0.6 (amd64)
** Affects: apt (Ubuntu)
Importance: Undecided
Status: New
