7.10 /usr/lib/cups/backend/hal failed

[n0body]

Binary package hint: hal-cups-utils

Hi!

My Printer worked fine unter Ubuntu 6.10 and afterwards with debian, but the new automatic detection with hal seems to have some bugs.

Printer is a Kyocera FS-1010, is correctly automatically detected and is listed in cups:

Beschreibung: Kyocera FS-1010
Ort: Local Printer
Marke und Modell: Kyocera FS-1010 - CUPS+Gutenprint v5.0.1
Druckerstatus: frei, Aufträge akzeptieren, publiziert.
Geräte URI: hal:///org/freedesktop/Hal/devices/usb_device_482_ 3_XAL4236975_if0_printer_noserial

But when i try to print anything, cups shows /usr/lib/cups/backend/hal failed

And the only message in the cups error log regarding this is:
[Job 19] Backend returned status 1 (failed)

I tried to uninstall the cups-hal package, but then the printer is not recognized any more.

Does anyone know how to fix this?

I also had some error messages in the auth.log, but after i disabled apparmour and SELinux, they are gone, but i still get this message.

Best regards

[mark (mt4167)]

I'm having similar problems.

Printer: Brother HL-5150D
OS: Fresh install of kubuntu 7.10 from the "alternative" disc (text install method) - as downloaded 2008-02-09.

I'm getting various problems - they seem to be permission related.

The problem goes away when I do the following:

# cd dev
# chmod 777 usb* usb/*

I can now print. I was unable to add the printer until I did this.

As soon as I reboot, the problem returns. The problem must be with hal/dbus setting the permissions wrong, and I'm sure I can fix it with a bit more effort. I'm reporting this as a bug because it's a fresh install, so I assume its not something I've done

Thanks,

Mark

[Peter T Hayward (energonic)]

Exactly the same problem as mark above. My printers are Epson DX3800 and Brother HL-1250. Both worked under Feisty. Under Gutsy they are detected and set up. Try to print a test page and I get the error "/usr/lib/cups/backend/hal failed".
These printers work normally under SUSE 10.3 and MacOSX on the same computer so this is down to Ubuntu software or its configuration.
As Mark says it works if I open up permissions on the usb devices but this is not the full solution.
Printing is a core function, is this going to be addressed soon?

[Peter T Hayward (energonic)]

If anyone still has this problem I found the solution in Ubuntu forums (but unfortunately didn't take their name- post appeared during 2006 I think).
The problem is that /dev/usb/lp0 does not have rw permission for logged-on user.

The solution starts by editing /etc/udev/rules.d/permissions.rules.

Under # Printers and Parallel devices, one line must be changed:
BUS=="usb", KERNEL=="lp[0-9]", GROUP="lp"
becomes
BUS=="usb", KERNEL=="lp[0-9]", GROUP="lp", MODE="0666"

It is possible you also need to create the lp group (I did) and put yourself into the lp group.

After this the device is accessible permanently.
Hope this helps someone - and gets the solution into the next release. Why do only a few people post the problem?

[Michael S Costello (fraterm)]

Same problem here on 64 bit 7.10, Brother HL-5150D_series, quite frustrating though as this did *not* fail until a recent update and some hal/dbus updates I saw. Perhaps the problem was fixed and now regressed. Will be trying the workaround mentioned in Peter T Hayward's note. Troubling because printing was so easy before, and this kind of thing gets on my nerves quite a bit when the formerly slick and easy becomes terribly broken, especially when one's art deadline is fast approaching. :(

Seems that the udev configuration file is now 40-permissions.rules (ordering) and the syntax is moving as well, with BUS being now the more generic SUBSYSTEM

So, what worked for me... ahem:
SUBSYSTEM=="usb", KERNEL=="lp[0-9]", GROUP="lp"
becomes:
SUBSYSTEM=="usb", KERNEL=="lp[0-9]", GROUP="lp", MODE="0666"

Slightly newer udev and syntax seems to have bit me and maybe many other users, but the effects are quite annoying, the printer will be automatically discovered, added to cups configuration, and promptly indicate readiness, and will defy any attempt to actually print until you add the lp group add your user to lp group, and perform this permissions modification followed by a sudo /etc/init.d/udev restart ; sudo /etc/init.d/cupsys restart. Status: /usr/lib/cups/backend/hal failed is replaced with Status: Ready:

Quality control wrt printing is essential, as users get a big throbbing frustration when their printing subsystem dies because of what seems to be a trivial update of core system services. This made ubuntu look bad in front of my pen and paper gaming group, who could formerly print character sheets, and various other nerd etceterata from their windows machines to my box with minimal trouble, and now had to lug their laptops up to my room to attach usb cabling manually.

[mark (mt4167)]

I managed to "fix" this one by doing the following (as root or with sudo):

# dpkg -l | grep cups

remove all of the above listed packages with:

# dpkg --purge <package names>

then reinstalling cups:

# apt-get install cups

I think one of the packages I had installed (cupsys-hal perhaps) was causing problems. After removing all packages cups related, and reinstalling the minimum necessary to do the job, things started working again.

I still consider this to be a bug - perhaps there is an undocumented conflict happening.

[Till Kamppeter (till-kamppeter)]

mark, after removing and reinstalling everything, did you also reinstall hal-cups-utils?

Michael S Costello, does it also work for you if you use

SUBSYSTEM=="usb", KERNEL=="lp[0-9]", GROUP="lp", MODE="0660"

in /etc/udev/rules.d/40-permissions.rules?

Everyone suffering this bug, can you post the output of

ls -l /dev/usb/lp* /dev/usblp*

and

ls -l /usr/lib/cups/backend/hal

[Till Kamppeter (till-kamppeter)]

Can you also try to add the user "haldaemon" to the group "lp" (in /etc/group)?

I got the same problem exactly since Sunday 16th march.

I don't get access to the printers usb device in my case:
Bus 003 Device 008: ID 04e8:3252 Samsung Electronics Co., Lt
not as user (member of groups lp and lpadmin) nor as root!!

I cannot figure out who is blocked using that device for i cannot find a user not beeing member of group lp when i ask lsof.

lsof | grep cups
lsof | grep usb

before sunday I was printing happily beeing member of group lpadmin only

I can solve it by opening permissions to
crw-rw-rw- 1 root lp 180, 0 2008-03-20 21:58 /dev/usb/lp0
either by hand or adding MODE="0666" in
/etc/udev/rules.d/40-permissions.rules
as described above .

I added haldaemon to group lp - no effect. This seems not to be a haldaemon problem.

I met this topic because i desperately was installing hal-cups-utils.

Without I get
"Drucker ist nicht verbunden, erneuter Versuch in 30 Sekunden …" which means
"Printer not connected Try again in 30 seconds.."

I'm sure, this is the same problem but perhaps I fail :o))

Ask if you need more details
