Problem installing software in Kubuntu 13.04
Having a problem installing software (Gimp, but tried others with same result). Software manager saying 'Waiting' and not doing anything. Tried apt-get and got these error messages:
E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/cache/apt/archives/
Grateful for any suggestions.
