HPLIP

A required dependency 'python3-pyqt5' is still missing

Asked by Robert Stagner

When I attempt to install HPLIP (v3.23.8) on my Ubuntu 22.04 system, I get the following errors

error: A required dependency 'python3-pyqt5 (PyQt 5- Qt interface for Python (for Qt version 4.x))' is still missing.
error: A required dependency 'python3-dbus (Python DBus - Python bindings for DBus)' is still missing.
error: Installation cannot continue without these dependencies.

Yet, when I check to see if these dependencies are installed
$ sudo apt list python3-dbus python3-pyqt5

Listing... Done
python3-dbus/jammy,now 1.2.18-3build1 amd64 [installed]
python3-pyqt5/jammy,now 5.15.6+dfsg-1ubuntu3 amd64 [installed]

So, the dependencies are INSTALLED :-). What am I missing or what am I doing wrong?

If you are running Ubuntu, then you better install the modified HPLIP package from the Ubuntu repositories instead of the original package from the HP pages (unless you need the newest version for your devices).

sudo apt install hplip hplip-gui

Thanks. Installing hplip and hplip-gui worked for me!!

Where is this information located in the documentation? I seemed to miss
this bit of information.

It is general advice for Ubuntu systems, to install software from the Ubuntu repositories whenever possible, because that has been verified to work with other Ubuntu packages.

Can you help with this problem?
