Hi @Ben7230, Unfortunately, the only distro supported officially is Ubuntu.
However, other forum members have successfully ran Manager on other distros, so I will keep this post open so any Linux experts could help you out but then again, no guarantees.
Edit: Fedora is also supported up to version 33 as of the date of the screenshot.
Out of interest, I tried this on Suse Tumbleweed in a vm
Used Yast to search for “libwebkit” and installed whatever it offered, following which Manager works just fine.
My foo with anything using the more modern versions of the Gnome DE (ie v3 onwards) on any base is not really up to snuff, but I would be willing to bet that the principle will still hold good.
I noticed that the error relates to “eto.GtkSharp…”. An old post in the forum related to Fedora 2.7 RPM broken on Fedora 27 - webkitgtk no longer provided had a similar problem and seems to have been fixed by @eto 5 years ago… I am wondering if your laptop was a complete fresh install of Fedora 37 and the other computer with the error one that got updated over time.
It seems more an isolated problem with one of your systems and that is beyond Manager to resolve.
