Use lxqt-sudo instead of pkexec as switch user command.
Summary: pcmanfm in Lubuntu used gksu. When we switched to lxqt, it had been deprecated, so we used pkexec. Unfortunately, pkexec just flat out fails. Looking upstream, they use lxqt-sudo, which we have in our install, so going with their default instead.
- Open pcmanfm-qt
- Click on "Tools" in the menu
- Click on "Open as root"
Should get an lxqt-sudo dialog asking for a password.
