@cpollock, I don't know your situation specifically so I would be speculating at best. But, if I were in your position I might do the following (but only do these steps at your own risk and have backups of your data elsewhere):
<risk> 1. delete any and all listed printers in your printer manager. 2. purge the foo2zjs drivers (I'm not familiar with the "correct" way of doing this so ask someone else.) 3. ensure hplip is fully-purged from your system by doing something like a "sudo apt purge hplip hplip-data" 4. now, install hplip and use hp's own drivers as explained in #22. Something curious from your log: hpmud is a component of hplip so perhaps it was installed at one time and wasn't properly purged before you installed the foo2zjs drivers and now colord is complaining that it can't see your 1020's color profile because foo2zjs isn't allowing it (pure speculation again.) 5. If those steps don't solve it, then perhaps purging and re-installing cups and then re-doing the steps over again might. </risk> Good luck. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to colord in Ubuntu. https://bugs.launchpad.net/bugs/1442050 Title: (colord:832): Cd-WARNING **: failed to get session [pid 690]: Unknown error -2 Status in colord package in Ubuntu: Confirmed Bug description: Get that error logged into journalctl (colord:832): Cd-WARNING **: failed to get session [pid 690]: Unknown error -2 ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: systemd 219-6ubuntu3 ProcVersionSignature: Ubuntu 3.19.0-12.12-generic 3.19.3 Uname: Linux 3.19.0-12-generic i686 NonfreeKernelModules: nvidia ApportVersion: 2.17-0ubuntu1 Architecture: i386 CurrentDesktop: GNOME Date: Thu Apr 9 11:57:02 2015 Lsusb: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 002: ID 046d:c50e Logitech, Inc.
