YouTube

Platform: Linux Mint 20.3

Nuclear version: 0.6.17; Appimage with AppimageLauncher

Description of the issue: I can't say that I really if I do things correctly, but it appears to be riddled with problems at my machine. At the very start of the appimage (and the .deb package previously) there's is an "Cannot read property 'sourceName' of undefined" error. But now a more serious issue appeared.

~/.config/youtube-dlg should just contain configuration files and not logs (which should go to $XDG_DATA_HOME/youtube-dlg/ ) nor youtube-dl binary (which should go to $XDG_CACHE_HOME).

Please also consider using appdirs instead of hardcoding ~/.config/

I found no other issue with this being asked.
