space on disk running low error logging /var/log/cups/error.log
I have Lubuntu 16.10 installed on my disk mounted as /.
The problem is that the CUPS log file( /var/log/cups/error.log) grows all the time until I no have free space left on the disk...
So when I delete that file, the space on disk freed up again
I already tried:
fsck- disk usage analyzer
- every apt-cleaning/autocleaning, and dependencies fixing.
How should I proceed?

Solution 1:
I had the same problem. The log files grows very quickly and after a few hours it consumes all available space in /. At this point things start going really bad. Also the cups process hogs the CPU (100% in one core - that explains the 50% you see in a dual-cure).
Deleting the file at this point doesn't seem to help immediately. I guess the file is still in use by the cups process and it won't free the disk space... but after a reboot I got some free disk space and had time do investigate /var/log/cups/error_log.
Here's what I found in the first few lines

And then the last warning is repeated over and over again... over 45000 times per second! (No wonder the disk is filled after a short time)
Assuming you have a similar problem, note that the thing cups keeps complaining about is very simple to fix:
Directory \"/usr/lib/cups/notifier\" has insecure permissions (040775/uid=0/gid=0).
Once you change the permissions with sudo chmod 755 /usr/lib/cups/notifier, the file should stop growing. (while you are at it, fix the other files it complains about).
