There are some old db files in /var/tmp/pamac/dbs/sync from the deprecated community repo & mesa-nonfree that I do not need anymore. cleaned out the old files

pamac upgrade gives the same error.

The folder /var/tmp/pamac/dbs/sync is owned by root with these permissions: drwxrwxrwx files inside are owned by the user.

I would expect pamac to ask for elevated rights as usual.

for me /var/tmp/pamac is owned by “$user” as all subdirectories and files (except files in symlink /var/tmp/pamac/dbs/local/)


But how does the ownership change?
Incorrectly using sudo pamac is a first thought. But then again.
We have other examples of it changing between users on a multi-user system as well.
(so then user A cannot access because the path is owned by user B)


I might have done this a few years back, the behavior is recent, maximum a week. Checked shell history and have not used sudo in combination with pamac.

Changing the ownership of /var/tmp/pamac/ to the $user with
sudo chown -R [user] /var/tmp/pamac/ and running pamac upgrade does not show the error anymore.

Some changes were made to libpamac a week ago.
