Comment 5 for bug 572795

I tried deleting the entire cache and starting over but no matter what I do this always seems to end any attempt to upgrade. I tried to use synaptic to reinstall debconf but it was unable to saying "E: debconf: subprocess installed post-installation script returned error exit status 1"

This is what I got in terminal when I tried to upgrade that way.

Unpacking replacement debconf ...
Processing triggers for man-db ...
Setting up debconf (1.5.28ubuntu4) ...
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
