RM 9 on Linux - unable to publish

Hi, new to RM but trying to set up RM 9 on Linux. Have installed RM9 on Kubuntu (22.04) using PlayOnLinux. Can download and open a tree, edit etc. BUT, when I try and publish by clicking on the generate report button, nothing happens. Has anyone else run into this issue and is there some sort of solution or work around?
