Fix Ubuntu package cache
Had problem with Ubuntu package cache.

Error! E: Malformed Description-md5 line; includes invalid character '21!0a2ee344f1a65d3401a41cc0d42a7' E: Malformed Description-md5 line; includes invalid character '21!0a2ee344f1a65d3401a41cc0d42a7' W: You may want to run apt-get update to correct these problems E: The package cache file is corrupted
First tried to disable any extra package sources, but it wasn't helping at all. Problem was caused by broken package cache, so had to find a way to remove temporary cache.
Solution was found from old forum thread:
sudo rm -r /var/lib/apt/lists/* sudo mkdir /var/lib/apt/lists/partial sudo apt-get update
