Comment 8 for bug 1748598

I ran a HPLIP 3.19.6 script on my Debian 10.0 and encountered the same error. Despite attempting to install "python-qt4-dbus" and "python-qt4", the same persists. Trying to install "pyqt4-dbus" and "pyqt4" packages also ended up futile because they were not recognized.

So, I followed the same way as Marcello Messori's steps (as posted on 2019-05-30) above but only disabled installation for qt4. These were my steps:

(1) Run the script: ./hplip-3.19.6.run

(2) When the script prompts 'Please choose the installation mode (a=automatic*, c=custom, q=quit) :', I chose 'c'

(3) When the script prompts 'Do you wish to enable 'Graphical User Interfaces (Qt4)' (y=yes*, n=no, q=quit) ?', I chose 'n'

(4) When the script prompts 'Do you wish to enable 'Graphical User Interfaces (Qt5)' (y=yes*, n=no, q=quit) ?', I chose 'y'

For the rest of the other prompts, I chose default options (marked with *).

After that, it successfully installs, and I managed to execute the 'hp-setup' command nicely and thereby print a test page!
