We have a server running apt-cacher to help cache Ubuntu repositories. However, after about 2 years of usage the disk on the server has filled up. I discovered this after trying to update my Ubuntu desktop and got the following error:
503 apt-cacher: Cache Full
Here is how to clear the apt-cache cache.
sudo service apt-cacher stop sudo rm -rf /var/cache/apt-cacher-ng/ sudo mkdir -p /var/cache/apt-cacher-ng/{headers,import,packages,private,temp} sudo service apt-cacher start
