hplip software installation gets stuck on sudo apt-get remove libhpmud0 libsane-hpaio printer-driver-postscript-hp

What happens when you execute the command
sudo apt-get remove libhpmud0 libsane-hpaio printer-driver-postscript-hp
in a terminal window?

Hi, thank you for the reply!

I executed the command in terminal, here is what happened (sorry, it's in Croatian, I'll translate later):

tea@CrnaKava:~$ sudo apt-get remove libhpmud0 libsane-hpaio printer-driver-postscript-hp

tea@CrnaKava:~$

So, it asked me if I wanted t remove, I replied yes (D).
Then it says "Removing (uklanjam) hlip etc...."
After that "Processing signal for libc-bin etc..."
And if stops there, it doesn't say it's finished or succesful similar.

Is this ok? Is it done now? Should I try to run hplip again?

This looks good. Now re-try the hplip installation.

Hi, I tried but I got stuck again at another step:

tea@CrnaKava:~$ sh hplip-3.21.2.run

I also tried running the failed comment in Terminal:

It says "impossible to locate package python-pyqt5"

Hi, thank you for the suggestion. I did install the suggested version, hplip-gui but it wasn't succesfull in communicating with the device.

I added the printer trough the HP toolbox interface, and it didn't manage to print the test page - error communicationg with the device (code 5012). Also, on startup I got the message "No system tray detected on this system. Unable to start, exiting"

:(

That's now a different problem. Hplip is installed.

A version is installed but it's not the latest hplip version or the version I was trying to install initially.

A version is installed but it's not the latest hplip version or the version I was trying to install initially.

After installing the printer on another, Windows system computer, I managed to configure it to connect to the router, after which I managed to install it wirelessly, through the Ubuntu printer setting interface (not through the HP toolbox), and now it's finally working.

Thank you for the support!

Thanks Manfred Hampl, that solved my question.

#1 Thanks for the hint, it worked also for 21.04 and 21.10 and the hplip 3.21.8
