Package: linux-perf
Version: 5.16.3-1~exp1
Severity: serious
Hi!
This package has code in its postrm maintscript, which unconditionally
removes the diversion, which breaks as the rename cannot be performed
due to linux-base owning the file, and dpkg-divert refusing to
overwrite it. This is the error shown:

The dpkg-divert calls should be protected to run only on the relevant
actions on all maintscripts.
Thanks,
