Problem in creating a dual-boot system

[wtb32141]

I have GREAT news! My scanner under Ubuntu 22.04 now is working thanks to the help I got from Claydoh and Schwarzer Kater. I ran the 3 reinstall statements Kater recommended. All 3 worked flawlessly. I also ran the hp-plugin command, which Claydoh recommended. I previously was unaware of the need for the plugin. Thanks to both of you for your help!

[claydoh]

What do you think of that plan?

That is up to you
I imagine having HP's full suite would be useful for you, and it won't hurt.

Claydoh, I’ve been doing some homework on my printer/scanner problem. The homework consists of reading this document: “What is the HPLIP Binary Plug-In and How Do I Install It?” [https://developers.hp.com/hp-linux-imaging-and-printing/binary_plugin.html].

I did not run HP-Setup when I installed Ubuntu 22.04. So I think I should run HP-Setup instead of HP-Plugin. Both commands will install the plugin (3.15.4) that’s needed to get my scanner going. I propose to run HP-Setup on Ubuntu 22.04 and Ubuntu 16.04 (that is, once I get 16.04 installed). What do you think of that plan?

Instead of using Muon or Synaptic as a frontend for the APT package manager you could also use it directly through a command line interface:


To be sure that HPLIP and its graphical user interface are installed as they should, you can open the Konsole terminal emulator from the
-> Application Menu -> System and enter (exactly as written)

sudo apt reinstall hplip (press [Return] and enter your password)

sudo apt reinstall hplip-gui (press [Return] )


To install python3-pyqt5 as claydoh suggested you could also use Konsole and enter

sudo apt reinstall python3-pyqt5 (press [Return] )
(it is already a dependency of hplip-gui - it does not hurt to check this explicitly, though)


PS: I suggest to use apt reinstall instead of just apt install to re-configure the packages.

[claydoh]

Muon is a graphical package manager that has been included with Kubuntu since 2010 .You already have it. It is a GUI for apt.
While Discover is an "app store", Muon and apt are used for 'advanced' package management tasks.

[wtb32141]

You ask: "What happens when you use Muon to try installing python3-pyqt5?"

My answer: I have no idea. I don't even know what Muon is, but I'll read about it tonight.

[claydoh]

I'll go to HP's site and see if I can find the latest version of HPLIP.

Oh my, that can be a decent undertaking.....

Option Description
---------- --------------------------------------------------
d Download plug-in from HP (recommended)
p Specify a path to the plug-in (advanced)
q Quit hp-plugin (skip installation)

Enter option (d=download*, p=specify path, q=quit) ?

If I enter "hp-plugin d", presumably it will download the plugin from HP.

Yes, hitting 'd' at his prompt would do that. This is basically what the GUI would be asking you, and then doing.

What happens when you use Muon to try installing python3-pyqt5?
That package would allow the GUI to open, though it isn't necessary for the task at hand, as you can still install the plugin via this command-line process.

Installing the full HP printer suite may be useful as well, hplip-gui.
Upgrading the the latest version manually is not a terrible idea, but since it was working with the much older version to begin with, there really isn't a strong reason to try that up front, in my opinion.

[wtb32141]

Thanks for the clarification. I never would have thought of that.

[Schwarzer Kater]

The difference would be that your version is packaged by Ubuntu and made available in their repositories and the other one is directly from HP.

… I just checked in 22.04: version 3.21.12 is the most recent one for 22.04 from Ubuntu - and there should be nothing wrong with it or your software updater.
In hindsight I would recommend to keep this version and try to download/install the plugin like suggested above.

All theory for me, by the way - I don't have any HP printers or scanners here…

[wtb32141]

After reading your note, I ran my software updater. It did not change the version of HPLIP that's installed on my computer. I'm running Ubuntu 22.04. It shows HPLIP version 3.21.12+dfsg0-1 as installed and as the latest version. I have great confidence in you; so I wonder what's wrong with my software updater! I'll go to HP's site and see if I can find the latest version of HPLIP.

[Schwarzer Kater]

Hm… Did you already try installing HPLIP version 3.23.8 (and go from there)? That is the most recent one.
See: https://developers.hp.com/hp-linux-i...nting/gethplip

I am in 22.04. Here is the response I get when I run hp-login:

[claydoh]

I hope you are OK!!!!!

It will be called python3-pyqt5 though it should be included in a Kubuntu 22.04 install already.
22.04 would not be using anything related to python3-qt4, though 16.04 did.

Can you post the FULL error message, or at least a screenshot?

[wtb32141]

Claydoh, please pardon my delay in answering your last note to me. I fell backwards in my home at night (in the dark), and I cut the back of my head when I hit a table that’s beside my bed. I’m feeling better now. I ran the hp-plugin command; it tells me that GUI modules PyQt4 and PyQt5 are not installed. They are unavailable in Synaptic; so I must look elsewhere for them.
