Comment 5 for bug 1471229

I use Mint 20 (fully updated) which is based on Ubuntu 20.04.

Even latest hplip 30.2.9 which claims mint 20 support, won't install fully as there are missing dependancies regarding python qt4. The problem is that qt4 is depricated and won't work correctly. Please move hplip to qt5.

The other option (I don't know if this is possible) is to try provide hplip as flatpak, snap or appimage.
