[SOLVED] system-config-printer failing

mdcclxv · 2024-05-01 21:32:43

Hi all,

Since like a week ago, when I try running system-config-printer it fails with the error bellow

  File "/usr/share/system-config-printer/system-config-printer.py", line 86, in <module>
    import cupshelpers
ModuleNotFoundError: No module named 'cupshelpers'

Found the following topic https://bbs.archlinux.org/viewtopic.php?id=295282 which looks exactly like my problem, except that upgrading to hplip 1:3.23.12-5 did not fix it. I have successfully cloned, built and installed the hplip code from the repo provided in that topic by user loqs and I'm still having the issue.

Anyone has any idea for a fix?

Thanks in advance.

The linked version is currently the repo one, https://archlinux.org/packages/extra/x86_64/hplip/ and the important part in loqs' link is the downstream patch https://gitlab.archlinux.org/archlinux/ … 18fb79bb6f
Make sure to restart cups after updating to that version.

mdcclxv · 2024-05-01 21:59:41

You kind of lost me here. The link provided by loqs is to a commit. Isn't that commit supposed to be already included in the repo I cloned?

I did restart cups. I even restarted the PC.

seth · 2024-05-01 22:03:27

You don't have to clone anything, just "pacman -Syu hplip" should get you the fixed version.
Let's where we're at:

pacman -Qikk hplip

mdcclxv · 2024-05-01 22:05:46

Here it is. Looks fine to me.

Re-installed hplip via pacman, same error.

seth · 2024-05-01 22:16:04

That looks like the correct package but just compiled by you (unnecessary, but should™ not make any difference)

Can you run hp-setup?
https://bbs.archlinux.org/viewtopic.php?id=295303

Do you use any other printer drivers?
(Did you even use hplip before?)

This error has to do with latest python 3.12.3. I read about this invalid escape sequence issue which is fixed by using raw strings.

No other printers. I did use hplip for the last year, it just worked.

pacman -Qo /usr/local/bin/hp-setup

You've some stale copy of hplip in /usr/local

mdcclxv · 2024-05-01 22:24:05

~: sudo pacman -Qo /usr/local/bin/hp-setup
error: No package owns /usr/local/bin/hp-setup

Haven't had such an issue up until now. While I do get what you're saying, no idea on what do I need to do.

seth · 2024-05-01 22:30:13

Get rid of the stale copy in /usr/local?

pacman -Qlq hplip | sed 's%/usr/%/usr/local/%g'

mdcclxv · 2024-05-01 22:35:53

You mean deleting everything that the command above printed?

seth · 2024-05-01 22:46:06

Almost. You've a stale copy in /usr/local that shadows the (updated) repo one in /usr and that is not under control of the package manager.

/usr/local/share/ppd/HP/ and /usr/local/share/hplip are gonna make the bulk of that list
/usr/lcoal/share/doc/hplip-3.23.12/ might be a different version, same goes for /usr/local/share/doc/hplip-3.23.12/ and /usr/local/lib/python3.12/site-packages/ and some of the point releases (eg. /usr/local/lib/libhpmud.so.0.0.6) - stay away from /etc and make sure to not just blindly xfer this - you'd delete the entire /usr/local that way.
The immediate offender are the matches in /usr/local/bin - the rest is likely just a clean-up chore.

Ok, hp-setup runs now. I still get the error when trying system-config-printer.

seth · 2024-05-01 23:02:57

Did you only delete the matches in /usr/local/bin or also the other stuff?

strace -f system-config-printer 2>&1 | grep '/local/'

might reveal what's still in the way.

The thing is that I get the same errors with any GTK theme, including Breeze.

mdcclxv · 2024-05-01 23:17:11

Deleted the other stuff as well.

seth · 2024-05-02 05:56:58

The "ENOENT" are just "is that file t here"?
There's no bogus augmentation left in /usr/local

type system-config-printer
PYTHONVERBOSE=3 /usr/bin/system-config-printer

nicks · 2024-05-02 14:27:56

This solved the issue for me.

It was an issue with system-config-printers and the recent python updates. Just a simple change of folders.

https://github.com/OpenPrinting/system- … issues/357

sudo ln -sf /usr/lib/python3.12/site-packages/cupshelpers-1.0-py3.12.egg/cupshelpers /usr/lib/python3.12/site-packages/cupshelpers

That's rather weird, though. Most users on that thread seem to use EOS, do you as well?

mdcclxv · 2024-05-02 20:03:55

The symlink trick fixed it for me as well, it's working now, although with all the errors mentioned on the github thread.

Thank you guys both for your time and effort.

seth · 2024-05-02 20:06:29

I'm not gonna hold that against you, but is this EOS?
Otherwise somebody needs to file a bug against the package, but this doesn't seem to be an issue for others who ultimately just ran into the hplip error.

mdcclxv · 2024-05-02 20:30:11

I'm not on EOS. Pure Arch here, installed from scratch.

Not sure which package are you referring to. Python? Cupshelpers? No idea who is actually responsible for the wrong name on that site-package.

seth · 2024-05-02 21:09:18

https://gitlab.archlinux.org/archlinux/ … r/-/issues
But w/ https://github.com/OpenPrinting/system- … issues/358 this might be a genuine upstream issue - though I don't really understand why it's not just for everyone.
Do you have some python packages installed via pip?
