Unable to install hplip due to Python-pyqt5 dependency

Asked by Edward J. Evans II

Installed HP LaserJet Pro MFP M479fdw without any problems. Printer functioned, scanner worked fine (but only for single page scans). The multipage function failed and the OCR failed. In trying to upgrade the hplip 3.20.3 to a newer version I failed every way I tried and I tried several versions up to and including the current 3.21.12 --- all efforts failed and now I am left with an incomplete hplip which doesn't work at all -- no printer and no scanner! and unable to complete ANY hplip install !!

According to https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index the HP Color LaserJet Pro MFP M479fdw is supported by HPLIP versions starting from 3.19.6.

There is version 3.20.3 in the Ubuntu repositories for focal and I assume that this will sufficient.

Try installing it with the command

sudo apt install hplip-gui

Mr. Hampl -
 Thank you for your fix - hplip intalled with no errors and now
the Printer works -- but the Scanner fails when selected for scanning
with an "Failed to open device xxxxxxxxxxx - error during device I/O."
when you select the LaserJet or if you select the Flatbed it scans the
flatbed but does not create any file.

Manfred -
I am sorry we are having this difficulty, below I have described how I
captured the data. I also attached 3 text files with the captured data
for each command you requested. I will pass them from my Linux system
to my Windows Outlook system and send you an E-Mail with the
attachments and also I will copy the text into the Outlook E-Mail
message in hopes that one of them will be formatted properly for your
system.
I am grateful for your efforts in trying to help me - thank you
RegardsNed Evans
Information you requested follows:

I am using Linux Ubuntu 20.04 LTS Operating system.
I am using the Gnome Terminal version 3.36.2 as my standard Ubuntu
Terminal window.
The first time I sent you the outputs that you said had no End-of-line
functions I had highlighted the Terminal window characters, copied them
and pasted them into the E-Mail. I am using the "Evolution" Email
program version: "3.36.5-0ubuntu1" and sent it. I received a copy of
that E-Mail at my windows Outlook system and it looked the same as I
sent it.
When you requested I resend it because of the no End-of-line functions
again I then highlighted the Terminal window characters as before but
this time I pasted them into a text editor, "GEdit 3.36.5-0ubuntu1"
 and then copied them from there into the E-Mail and sent it. I also
received that copy at my Windows Outlook system without any
issues.GEdit 3.36.2 text editor and saved the file

I suggest that you try the following:
Open the page https://answers.launchpad.net/ubuntu/+question/700017 with the web browser of your Ubuntu system.
Open a terminal window and re-issue the commands.
Copy the output from the terminal window and paste it into the "Message:"-box of the web page that you already have open - without any extra program.

Manfred -
 I have done as you requested and placed the Terminal output
into a Message Box on the WEB page and it all looks properly formatted
and readable.
 As I write this I noticed that my Evolution E-Mail code is set
for HTML and not plain text --- perhaps that was what was corrupting
the format.

Is it correct that you want to use the scanner on network address 192.168.1.104 ?

What do you get when you try using scanimage with that device, e.g. with a command like

scanimage --device='hpaio:/net/HP_Color_LaserJet_Pro_M478f-9f?ip=192.168.1.104' --format=jpeg > image.jpeg

Have you tried sane-airscan?
According to https://github.com/alexpevzner/sane-airscan your device should be supported.

Manfred -
 Thank you for the info and link to 'sane-airscan' I tried it
but failed because the package for Ubuntu 20.04 apparently doesn't have
a Public Key. I place the output in the WEB site and am looking for
where to go next --- maybe report a 'issue' on github ?

Didi you follow the instructions in https://software.opensuse.org//download.html?project=home%3Apzz&package=sane-airscan
Those are the four commands to execute:

echo 'deb http://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04/ /' | sudo tee /etc/apt/sources.list.d/home:pzz.list

curl -fsSL https://download.opensuse.org/repositories/home:pzz/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_pzz.gpg > /dev/null

sudo apt update

sudo apt install sane-airscan
