Hi,

I have just installed lubuntu 18.04 LTS, and I'm installing drivers HPLIP by command line using "sh hplip-3.18.6.run" command. The installation works fine until the launch of GUI for define printers.

Running hp-check i get:

---------------------
| Python Extentions |
---------------------

 cupsext CUPS-Extension REQUIRED - 3.18.6 OK -
error: NOT FOUND OR FAILED TO LOAD! Please reinstall HPLIP and check for the proper installation of hpmudext.
 error: hpmudext IO-Extension REQUIRED - 3.18.6 MISSING 'Not Found or Failed to load, Please reinstall HPLIP'

It seems as CUPS is uninstalled.

Then I run:
lamberto@ITPGAL204PU1:~/Scaricati$ hp-doctor

Traceback (most recent call last):
  File "/usr/bin/hp-doctor", line 39, in <module>
    from base import utils, tui, module,queues, os_utils, services, smart_install
  File "/usr/share/hplip/base/module.py", line 30, in <module>
    from . import tui, utils, device
  File "/usr/share/hplip/base/device.py", line 42, in <module>
    from . import status
  File "/usr/share/hplip/base/status.py", line 50, in <module>
    import hpmudext
ImportError: /usr/lib/python3/dist-packages/hpmudext.cpython-36m-i386-linux-gnu.so: undefined symbol: hpmud_make_par_uri

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/hp-doctor", line 44, in <module>
    log.exception("")
TypeError: exception() takes 1 positional argument but 2 were given

what should I do?

The whole output of hp-chech is attached

Tanks in advance

Hi Matteo,

Please try the below steps.
1. Uninstall the HPLIP by entering `sudo make uninstall`.
2. Do and OS update.
3. Download and install HPLIP latest driver and plugin from the site, https://developers.hp.com/hp-linux-imaging-and-printing/gethplip
4. Do hp-setup to add device.
See if it resolves the issue.

Thanks,
Srinivas Teja.

Hi Srinivas,
I will inform you about happens after my report of error.

I installed the restricted extras package, Libreoffice 6.0.5, VLC and so
on. I also defined my printer via lubuntu grafic interface and I uset it.

Then I rebooted my system and, magically, the icon of HPLIP status
service has appared in the lower right panel.

Note I have rebooted several time after erroneous installation of HPLIP
and before installation of others software packages, but nothing had
happened.
I tried HPLIP and it seemed work fine.
I deleted my printer by lubuntu ,  I defined the printer by hp-setup,
and it was defined whit fax functions and all other caracteristics. Now
all works fine.
I think that the installation of others softwares have installed
prerequisites of HPLIP make it active.

Thanks.
Lamberto
