Thank you for making this linux version available, it works perfectly on OpenSUSE Thumbleweed. Most of the instal problem can e solved by corectly instaling gtk-sharp or gtk-sharp2 on the linux system from my experience. Soemtimes the "mono .Net" package might be needed.
(Before, I had to use a windows VM on my linux for a long time simply to access escribe suite since the linux version don't run correctly or at all on RHEL 8/9 (I know kinda wierd to have RHEL as your workstation))
