stdout does not display `rpm -qa` output without redirect

Question

On a SLES 12 virtual machine the command rpm -qa does not return anything to stdout.

~> rpm -qa
~>

The command finishes after 1 or 2 seconds, so it clearly generates some data. Only when the output is redirected to a file or through a pipe it becomes visible:

~> rpm -qa > out.txt      # works fine
~> rpm -qa | grep lib
libgcc ...
...

The problem is not with the rpm DB, the DB files in /var/lib/rpm/ are existing and seem healthy, a rebuild as suggested here does not solve the problem.

maybe your shell is broken. Try `reset`. or just login again. — Chris Maes, Jan 12 '21 at 12:05

Turns out it was the rpm apparmor profile which caused this behavior. I disabled it temporarily and rpm worked again.
