Comment 51 for bug 1847142

Thanks for you advice.
I am not myself a linux guru and even if I also notice that installing and purging was quit surprising, I followed each process step and it worked, so I shared.

I'm not able to explain why it works but at least I can experiment : as I had a third computer to install drivers on, I tried to make it without the five sudo you thought unnecessary and I report.

First, I only installed the hp-plugin :
sudo hp-plugin -i

But scanimage -L didn't found the scanner, nor xsane.

Then I tried to remove hp-lip and reinstall only hplip (and its dependancies) :
    sudo apt install hplip
    sudo apt purge hplip
    sudo apt autoremove
    sudo rm -rf /usr/share/hplip
    sudo apt install hplip

But once again scanimage -L didn't found the scanner, nor xsane.

In then reinstalled plugin :
sudo hp-plugin -i

But still no scanner...

At least I restarted from the begining for the whole process (purge hplip, install libsane-hpaio, reinstall plugin) and then it works....

I can't explain why it works but it seems that each step is useful or at least one step in the process unlock something that make it work.

Best regards !
