2 months agoI could be wrong but no remote refs refers to not finding a repo for what you are trying to install, so either the flathub repo isnt added which it sounds like it is, or the app you want isnt in that repo.
So you may need to add the repo for that app: https://fcitx-im.org/wiki/Install_Fcitx_5
I agree with what others have said about using reaper. It really is a great DAW.
That said, a lot of good vst use stuff like ilok or other crap that makes it impossible or very difficult to use on Linux at least in my experience.
I made a windows box specifically for making music because its just way easier. Making music on Linux sucked for me due to crashing and the plugins I bought before I switched to Linux on my main machine.
Reaper should be fine for you, there are plenty of good Linux compatible VST but if you ever get “serious” about music production, Linux isnt quite there yet IMO. Windows would be my recommendation or if you can afford it, a Mac is good too from what ive heard.
