Network scanner (Canon) stops after upgrade from 15.04 to 15.10

Question

I have just upgraded Kubuntu 15.04 to 15.10 - all very nice. The machine is working well, and I can print to the Canon pixma mx420 with no problems as before, but both Skanlite and xsane return errors. xsane returns:

Failed to open device 'pixma:MX420_192.168.1.5': Invalid argument.

Also:

scanimage -L
device `pixma:MX420_192.168.1.5' is a CANON Canon PIXMA MX420 multi-function peripheral

So the system is finding the scanner at the correct network address, but I don't know how to debug further. Note this all worked well before upgrade on this machine and the scanner has been tested from another laptop on the same network successfully - which is still on Kubuntu 15.04.

Thanks.

Solution 1

It's a bug in a few versions of sane-backends (pkg libsane) which affects versions 0.17.10 - 0.17.18 (the last one actually present in 15.10). Since the bug has been fixed since July 2015 we just need it packaged in a debian/ubuntu repo. Until then there are several possible workarounds:

• Get a version of libsane, libsane-common and libphoto2-pack10 from vivid and downgrade. Vivid contains 0.17.4 and thus is not affected.
• Get a version of libsane, libsane-common and libjpeg62-turbo from debian experimental. I found the version 0.17.23 in it and it seems to work for me. But be carefull, its experimental :-).
• Build the sane-backends libraries by youself. Not a straightway method, you better get the debian packaging patch to get it into proper paths.
• Use ScanGearMP which apparently works anyway. Is suitable for simple scanning for example through GIMP.

Solution 2

I had the similar problem with the Canon Pixma MG5450 (MG5400 series) using Ubuntu 15.10.

Problem:

Using "Simple Scan" to scan a document failed with:

Failed to scan
Unable to connect to scanner

But the device was properly discovered using scanimage -L

$ scanimage -L
$ device `pixma:MG5400_C5BFDC000000' is a CANON Canon PIXMA MG5400 Series multi-function peripheral

Solution:

Download 3 packages from Debian Expirimental - Libs

• libjpeg62-turbo
  • Version: 1:1.4.80-115-gfb907b2-1
• libsane-common
  • Version: 1.0.26~git20151121-1
• libsane
  • Version: 1.0.26~git20151121-1

(My reputation won't allow me to add more then 2 links. Otherwise i would have linked those libraries.)

Install *deb packages

# #Install the downloaded packages as root
# dpkg -i libjpeg62-turbo_1.4.80-115-gfb907b2-1_amd64.deb
# dpkg -i libsane-common_1.0.26~git20151121-1_all.deb
# dpkg -i libsane_1.0.26~git20151121-1_amd64.deb

I had the similar problem with the Canon Pixma MG5350 (MG5300 series) using Ubuntu 15.10. Installing the Debian Expirimental - Libs works.

Just a slight update - I have also tried to use xscanimage from the command line and I get the same message as with xsane - I would guess that this is very much the same interfacing. My guess as a newbie is that the backend sane library is no longer talking to any of the frontend tools. This must be specific to my setup as I would think this would be spotted in alpha / beta testing ;-)

OK, sane-pixma v.0.17.18 does not work, v.0.17.4 does - downgrading packages libsane and libsane-common to vivid versions helped (and the libgphoto2-port10 as a dependency). Currently looking for a suspicious commit in libsane GIT.

[honkir]

Update: sane-pixma works since v.0.17.19 again (a version just after the one in wily). However I didn't find the newer version in a package anywhere.

[Paul Chaffey]

OK all working. I downloaded the 3 packages (libjpeg62-turbo_1.4.80-115-gfb907b2-1_amd64.deb, libsane_1.0.25+git20150927-1_amd64.deb, libsane-common_1.0.25+git20150927-1_all.deb) from debian experimental and installed them using sudo gpkg -i filename. Great answer - Many thanks Honkir

This answer is the most complete! It helped me with my Ubuntu 15.10 upgraded from 15.04 and issue with detecting scanner in Canon PIXMA MX870. Same issue has been resolved with the proposed fix. Well done, thank you!

[madjoe]

BTW, there could be a possible issue with TeamViewer's dependency, since it relies on libjpeg62 library.

[madjoe]

After reinstalling TeamViewer 11, Ubuntu removed Simple Scan and Xsane and offered me to REMOVE the following packages: argyll argyll-ref gnome-control-center-data gnome-settings-daemon libcolord-gtk1 libgoa-backend-1.0-1 xsane-common

[madjoe]

I posted a new question caused by following those steps: askubuntu.com/questions/739592/…

[Jonathan]

Unfortunately libsane-common is no longer available in Debian Experimental. Any other relatively sane source?

[Ashish Rawat]

These packages didn't work for me but askubuntu.com/a/798622/20924 did.

There are dependency problems with Ubuntu 16.04 and libsane_1.0.27 experimental refused to install, but the --auto-defonfigure option helped at the end. Now I'm scanning too. :)
