Description Alan Moss 2019-09-20 00:21:52 CEST 
Description of problem:


First I am a computer user not an expert.

I'm using mageia 6
computer is a Acer ES1-512 laptop
printer is an HP Deskjet F4580

Until recently when I click on the up arrow on the bottom task bar (next to clock) the status & notifications menu opened and had a link to HP device manager, This link has gone.

also when I open the start menu and go to "tools > system tools and click on HP device manager" nothing happens.

I don't use the printer very often but a week or two ago I used HP device manager to set the printer to print 2 pages per sheet now I cant find a way to reset it to 1 page per sheet.

I have tried deleting and re-installing the printer. HP print manager is still missing.
It prints the test page correctly it also prints a picture normally from Gwenview

Any help will be appreciated

Alan Moss 

I don't understand this. but the file that has the info is  

usr/share/hlip/data/models/models.dat

but for some unknown reason the computer has stopped finding it.

Thank you Barry for your quick intervention.
I am not sure that hplip is the relevant SRPM, but it looks likely. This has no maintainer, so assigning the bug globally; CC'ing Florian as someone who has dealt with it before.

Please provide the output of:

ls -l /usr/share/hplip/data/models

Check if you have strace installed:
rpm -q strace

If you don't have strace installed then you can install it with:
su
urpmi strace
exit

Then please also paste the output of:

strace -o hp-toolbox_strace.txt hp-toolbox && cat hp-toolbox_strace.txt|grep "models.dat"

(All one command)

Thanks

Yes I saw the 0, but my error too, sorry, the second part after && won't run if the first part fails, as in your case. /o\

Just run the following now:
cd
cat hp-toolbox_strace.txt|grep "models.dat"

and paste the output here.

Thanks.

Comment 9 Barry Jackson 2019-09-24 00:09:34 CEST 
This has been resolved in private communication.

Since Alan's hp-toolbox was looking for models.dat in ~/data/models/ we created that directory and copied models.dat into it.
This fixed the 'missing file' error but hp-toolbox still refused to run due to the "TypeError: 'NoneType' object is not iterable" issue.

After some Googling it appeared that https://bugs.launchpad.net/hplip/+bug/1719169 may have the answer, so we removed lib64sane-hpaio1 and allowed it to remove 3 other deps.

The printer was then reinstalled via MCC->hardware (which re-installed the packages) and now it is working correctly and hp-device-manager is again available from the status and notifications systray list.

Closing as resolved, although we still have no idea of the original cause.

Resolution: (none) => WORKSFORME
