CUPS is not running

[jjanderson5]

CUPS used to work for me with this release, but it does not seem to be working now.

When I try to enter the URL http://localhost:631, my browser tells me the url is not found.

I ran 'ps -elf | grep cups' and it did not find a process with 'cups' running.

I tried running 'sudo service cups start' and got:

start: Job failed to start

I also tried running 'sudo service cups stop' and got:

stop: Unknown instance:


It looks to me like the daemon is not running for some reason and that it will not start.

I check my package manager and CUPS is installed, and I upgraded to the newest release today, but still
got the same results.

I would appreciate any suggestions. Thank you.

Re: CUPS is not running

The CUPS documentation explains how to enable error logging. Then take a look in /var/log/cups and you might discover the problem.

Steve,

Thank you for the suggestion, but I believe the logging that you referred to is the access logging for CUPS, i.e. it logs the activities of CUPS once the daemon is started. My problem is that the daemon will not start. I did check the /var/log/cups directory and there was no log there that would give a hint for the start up problem.

Re: CUPS is not running

Does cups start if you launch it manually:

sudo /usr/sbin/cupsd

any error message?

Re: CUPS is not running

Open a console and just reinstall cups:

sudo apt-get install --reinstall cups

Then reboot and check to see if Cups is running.

Hi snowhog,

I tried running 'sudo apt-get install --reinstall cups' and got

Clearly, something is still wrong. I tried running, 'sudo /usr/sbin/cupsd' as kubicle suggested and got the following
error message:

/usr/sbin/cupsd: error while loading shared libraries: libcupsmime.so.1: cannot open shared object file: No such file or directory

I'm thinking it may be time to upgrade to Kubuntu 11.10 and start anew.
