Public bug reported:
This is about issues with Canon's Maxify MB2320 drivers for the printer
and scanner. Something puts a large number of files in /var/tmp,
whenever the printer or scanner functions are used. These files all
start with cnij. The scanner driver is not Sane compliant. To scan the
Canon app must be called from a terminal with:
scangearmp2
running that produces: "(scangearmp2:11008): GLib-CRITICAL **: Source ID
1019 was not found when attempting to remove it"
I have posted about this at the Canon community forum and this forum
today (23 Feb 16).
Per Launchpad requirements:
mark@Lexington:/var/tmp$ lsb_release -rd
Description: Ubuntu 14.04.4 LTS
Release: 14.04
mark@Lexington:/var/tmp$ apt-cache policy scangearmp2
scangearmp2:
Installed: 3.00-1
Candidate: 3.00-1
Version table:
*** 3.00-1 0
100 /var/lib/dpkg/status
I have asked the Canon forum to better work with Linux developers
towards writing Linux compatible software. I expected the Canon to be
Linux compliant, not to have Canon try to make Linux comply with Canon.
These cnij* objects in /var/tmp became so numerous (305) that I received
a " / is full" message. That required posts at UbuntuForum.com to
resolve that problem. The 305 cnij* created 1.7gig of file space in
/var/tmp. This problem must be temporarily resolved by: cd /var/tmp and
then sudo rm cnij*. Then ls to see that the cnij-s* are gone.
