Description

While testing the fix for Bug #10893 I noticed that printing still doesn’t work for me: with a HP printer that worked fine for me on Debian Jessie (some months ago) and currently works fine on Debian Unstable, I get this in the journal when plugging it:

Jan 18 02:36:29 amnesia colord-sane[6910]: io/hpmud/musb.c 2075: Invalid usb_open: Permission denied


Two (!?) entries shows up in GNOME’s Add Printer settings, and when I try to add any of them I get a generic failure pop-up, and I also see this in the journal:

Jan 18 02:39:31 amnesia gnome-control-center.desktop[5617]: (gnome-control-center:5617): printers-cc-panel-WARNING **: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.fedoraproject.Config.Printing was not provided by any .service files

I’m optimistically assigning this to you intrigeri, since I suppose you have some sort of experience from the current printing situation in Tails after Bug #10893.

Well, no, I’m not really familiar with the printing situation: so far I only fixed AppArmor profiles. I can have a look, but without access to the hardware it’ll be hard. Sorry :/

Please set target version back to 2.0 and reassign to me so I try to fix it, if this is a regression against 1.x.

I would gladly help, if you have any idea what to test or where to look for more useful info.

I can add the printer without issue in 1.8.2. I had to set an administration password, though, which I didn’t in 2.0~rc1 (I know I set one but wasn’t prompted).

I’ll try to give it a look for 2.2. No promise, though. Help is welcome.

a user report the same issue with an Epson printer. It worked well on 1.8.2, and I found the same warnings in the logs.

Good news, it’s solved after the installation of system-config-printer.
Note that there were some good reasons to remove this package 5 monthes ago: https://labs.riseup.net/code/projects/tails/repository/revisions/84c0feb87eeb4f5472b60c4b04bf92291c49a2f6

Done, reassigning to you, intrigeri, tell me if I should rather add you as ‘Watcher’.
Cheers

Thanks. That’s OK. The target version is very optimistic though, adjusting it (and even 2.4 feels optimistic, feel free to go find help elsewhere).

Another user reported that issue with the following hardware:

Epson L220 and TX235

FWIW I can add an OKI printer connected to the local network (no USB)

  • Status changed from Confirmed to In Progress

Reproduced locally by plugging a printer via USB, but not when using it via the network, which is why I missed the problem when I worked on Bug #8443 and friends. So, apparently for some printers system-config-printer is still needed:

Installing system-config-printer allows GNOME printer config to go one step further (“Installing”), but:

  • if we install it, we need to drop its desktop file to avoid re-introducing Bug #8505;
  • then, a few TCP packets to 140.211.169.27:443 (reverse DNS: openprinting2.linux-foundation.org) are blocked by our firewall, scp-dbus-service segfaults and the installation of the new printer fails; these packets are sent as the amnesia user, so we can’t trivially transparently proxy them through Tor.

Note that the installation “succeeds” (although the correct driver is not selected) if I click “Cancel” in the “Searching for drivers” dialog.

Then, if I torify scp-dbus-service in /usr/share/dbus-1/services/org.fedoraproject.Config.Printing.service, I see connections to the aforementioned IP address in Onion Circuits, and the printer installation succeeds; however, the correct driver is not selected. I guess it’s just because the printer I’m testing is not known neither locally, nor in the openprinting database; and indeed on sid, this works just fine, because my printer’s PPD is shipped with newer hplip (same on Tails after installing from jessie-backports a bunch of packages: hplip printer-driver-hpcups libsane-hpaio libhpmud0 hplip-data hpijs-ppds printer-driver-postscript-hp).

At this point I cannot confirm that torifying scp-dbus-service is enough to make it do anything useful, but at least it prevents it from segfaulting, and allows me to configure one printer (known in the local database) that I could not configure otherwise, so it’s already progress.
