Some users in Fedora have reported to have authorization problems with current version of PM: https://bugzilla.redhat.com/show_bug.cgi?id=1575385 https://bugzilla.redhat.com/show_bug.cgi?id=1639020 I don't know if you want to bother with that, since I've tested both problems disappear by using the kauth experimental branch. Is there any ETA for that branch to become stable?
ETA for kauth braunch is not available yet as I don't know when smartmontools will be relased. That said, neon team wants me to harden kauth helper security before I release. For now I've added command whitelist, but some commands (mv, dd, CopyBlocksHelper needs hardning too... Maybe disallow writing to /usr/ /bin/ /sbin/ /etc /opt /var/ /dev, although I need to allow /etc/fstab) #1575385 sounds like downstream problem. There is nothing KPM can do if kdesu is not properly configured according to sudo configuration. Unprivileged user has no way of knowing if root account is enabled/disabled. The second issue is also known to me. It's either connecting to dbus user bus or dbus root bus. Either way breaks something on modern systems.
Let's close this as unmaintained as there isn't much I can do without KAuth.
