I’ve set up my 5th Ubuntu-Mate 16.04 system yesterday and ran into an unexpected problem. Everything was fine at the initial reboot so I started installing updates and some extra software for my wife. When I rebooted I was greeted with a nasty “Starting Caja…” endless loop filling up the bottom taskbar
Eventually I was able to sudo killall caja to stop it, but then caja wouldn’t launch.
Remembering the only two things I’d added for her that I didn’t for myself, I removed caja-dropbox and caja started working. Thought I was done and shut down for the night.
Rebooted this morning and sure enough the caja starting loop was going again. Another, this time more difficult, sudo killall caja stopped it. So I removed antivirus from Software Boutique. This got caja working again and after this I wasn’t met with the starting caja loop after I rebooted.
Don’t know what is really going on here but I’d like to point out the issue and my solution that might provide a clue, or help others with the same problem.
I ran into this starting caja loop when I initially tried Ubuntu Mate 14.04 on top of Ubuntu 14.04 which made me ignore Mate until I tried 15.10 in anticipation of 16.04, having found nothing that would be a suitable replacement for the old Ubuntu 10.04 systems we’d been using to great success.
