I installed partitionmanager 1.2.1 from the official repositories on KDE Neon 5.6.5. Reproducible: Always Steps to Reproduce: 1. Plugged an USB drive 2. Made partition changes 3. Pressed apply Actual Results: It gives an error if I try to apply since I'm not running as root. I don't even get the "unmount" option in the context menu. Expected Results: This program should always ask for root privileges for the partition manipulation to work.
Probably because kdesu doesn't work in Neon, assigning to Neon Newer versions of Partition Manager might work without it?
It looks like this is caused by a combination of 2 things: kf5 based kdesu is not in $PATH kde partition manager in neon is too old (only 2.0.1 and later can find kdesu in libexec folder)
Closing this since Partition Manager has been updated to version 2.2.1 automatically.
