Bug#954807: apt upgrade sometimes marks packages as manually installed

2020-03-23 Thread Piotr Engelking 
Package: apt
Version: 2.0.0
Severity: normal


When a package listed as an argument to apt upgrade is already at the
requested version, it is marked as manually installed:

# apt-mark showmanual libc6
# apt upgrade libc6
Reading package lists... Done
Building dependency tree
Reading state information... Done
libc6 is already the newest version (2.30-2).
libc6 set to manually installed.
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
# apt-mark showmanual libc6
libc6
#

Please do not mark packages listed as arguments to apt upgrade as
manually installed.

Hmm... What is the difference between apt install  and apt upgrade
, then? I would naively expect the first to mark the package as
manually installed, and the second not to. Is there a way to to upgrade
a package to a particular release without marking it as manually
installed?

Also, when the package listed as argument to apt upgrade is not at the
requested version, it is not marked as manually installed, exactly as I
would expect.
