Bug 1196237

I think this is due to the port to python3 not being complete. but it prevents me from using my printer on any Fedora 22 machine

I rebuilt hplip-3.15.2-6.fc22 using python2 and not python3 and it is working fine. Please revert python3 support in f22 and fix things in rawhide

Obviously we'd rather have the Python3 build working if possible. It looks like it might just be incomplete dependencies due to the plugin bringing in ones we can't know about, e.g. "error: Python gobject/dbus may be not installed"

Could you see whether installing e.g. python-gobject, or python-dbus, or both, fixes it?

they were all already installed. it changes nothing.

OK, looking at this, it seems that the problem is with hpmudext only being a python3 module, and the downloaded plugin installer being python2.

Reported upstream:
  https://bugs.launchpad.net/hplip/+bug/1434224

As a work-around, we'll add a new hplip-compat-libs sub-package for the Python 2 module.

hplip-3.15.2-8.fc22 has been submitted as an update for Fedora 22.
https://admin.fedoraproject.org/updates/hplip-3.15.2-8.fc22

after installing the update hp-plugin still fails to install the plugin, there is something still missing.

Installed:
  hplip-compat-libs.x86_64 3.15.2-8.fc22

Still doesn't work. In GUI mode it displays a grey dialog and a bunch of errors:

in 'interactive' mode it repeatedly does this when you tell it to download the plugin:

Yes, I can see this with all hp-* commands that are supposed to be run as root and that have any graphical output. Even with older hplip-3.14.10. Seems to be some Qt/PyQt problem.

I haven't been able to figure out what's the culprit, but it seems to be ok with 3.15.4 (http://koji.fedoraproject.org/koji/taskinfo?taskID=9493349).

Note: I don't think any of the graphical HPLIP tools are meant to run as root, are they? The way it's supposed to work is that a udev rule grants the console user an ACL on the USB device node.

er, yeah, they are, hp-plugin explicitly tells you to run it as root if you try and do anything else:

error: You must be root to run this utility.

Ah, OK, I guess that one's special because it wants to write to root-owned directories.

I think I was getting confused with hp-toolbox, which shouldn't need to run as root.

Thanks to Andrew Travneff, the graphical-app-shows-up-grey part of this bug is likely https://bugzilla.redhat.com/show_bug.cgi?id=1185893 .

Hi,

About this being related to bug 1185893, this has been discussed on the xorg-devel list and we do not consider this an Xorg bug, the problem is lack of proper error checking of the MIT SHM extension related X calls in the app / toolkit. This actually is a feature because people are now getting proper protection of unauthorized accesses to their shared memory segments where before anyone could access them (as the X-server was doing the accessing and it ran as root).

Also gui apps should really not run as root, ever. I realize this is sometimes easiest, but we should not ship anything setup this way ootb and/or depending on this (running as root).

Note I've also discussed this with the some qt people and it is fixed in qt5, and currently there are no plans to fix this for qt4, there answer to this problem is: Do not run gui apps as root.

Note that there is a workaround  for qt4 described in bug 1185893:

kcalc --graphicssystem native

So this can be worked around by making the hplip utilities to the same from code, and / or modifying the launchers. This is a workaround though and in the long run the need to run gui code as root should really be dropped.

Regards,

Hans

hplip-3.15.2-9.fc22 has been pushed to the Fedora 22 stable repository.  If problems still persist, please make note of it in this bug report.

It now works OK as 'hp-plugin -i', but it still has the X problem in graphical mode. I'll file a new bug for that.

Reopening since it's still not working with hplip-3.15.2-9.fc22.x86_64.

hp-plugin still says "file does not match its checksum" and fails to install the "plugin" that would allow the printer to actually work.

I can see several similar upstream reports, with a reply that Sourceforge site is down and to download & install the plugin manually.

I've contacted a HP and they claim that such bug is fixed already since 3.15.4 release of hplip, it should be safe now to drop hp-compat-lib package from hplip.

Since I have the same issue on F22, I created a F22 RPM with copr (https://copr.fedoraproject.org/coprs/neteler/hplip/) using the SRPM from http://koji.fedoraproject.org/koji/packageinfo?packageID=205

Still there is a dependency issue:

What am I missing?

Any chance to get the hplip-3.15.7-5 in FC22?

I cannot install the plugin... and so cannot use the printer

Maybe you are seeing bug #1249414 ?

I still can't find what is going on, because I was able to install on another FC22 computer.
