I am using Ubuntu 18.04 and installed 20.04 alongside, in a new partition. However I now realize that this is a mistake. All data is still in 18.04 and 20.04 is empty, it is not an update as I mistakenly assumed. I now understand that I must wait for the dot version of 20.04, to update my former version. My question is: How can I safely delete the new partition with 20.04 again?
My HP Laserjet Pro MFP M26nw worked fine with Ubuntu 16.04 but since I installed 18.04 only the print function works, I cannot get the scan function to work.
Simple Scan says "failed to scan" and the HP Device manager tells me: Driver required.
Clicking next returns: Failed to install plugin.
Running hp-plugin from the terminal and downloading returns: failed to load module "canberra-gtk.module". Plug-in installation failed.
Does anyone know how to solve this? I have the latest version of HPLIP.
