alfisya Can you please try to install those and see if it launches?
Only one rundep was missing. Here's what the eopkg command looked like.
I thought it might be a GNOME vs. KDE issue, so I checked it on my Xfce laptop as well. I remember when I installed it on the Plasma machine, three packages were instaled. On Xfce, only one was. But the result was the same - i.e., installed in the menu, but unable to launch. I'm going to try adding those two packages now, and see if that cures it on Xfce as well. (I need to end this here, and edit it on the other laptop after I try this there.)
On the Xfce machine now. Here's what the eopkg command looked like here.
Even though the theme for this laptop is set to Qogir-Dark, it's obviously not paying any attention to that. But that's the subject of another bug report that I filed. It appears I can't do anything about it.
