I'm getting an error which is I believe similar to this one, however an upgrade or dist-upgrade won't solve it as I've already got the latest version.

I'm running Ubuntu 12.04 and fuerte.

When running roscore I get the following output:

WARNING: unable to configure logging. No log files will be generated
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
