Known issues

Arch Linux XFCE despite having xdg-utlis package was lacking xdg-user-dirs. It could've been bypassed by modifying the installation script and setting DOWNLOADS_DIR as ~/Downloads or wherever the .deb file's been saved, though I wanted to keep this installer as user-friendly as it could get.

Arch Linux XFCE lacks full qt5. You have to install it first by running sudo pacman -S qt5 and selecting all (I haven't figured out which one exactly solved the issue).

Feel free to report bugs.
