Release: Description: Ubuntu 14.04.1 LTS Release: 14.04 2. not a package. The whole distro is broken. 3. I always expect apt-get update to work, at least with Ubuntu's own repositories. 4. "apt-get update" failed, and later "apt-get dist upgrade" It started with this when doing a normal "apt-get update" W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty- updates/main/source/Sources Hash Sum mismatch W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty- updates/main/binary-amd64/Packages Hash Sum mismatch W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty- updates/universe/binary-i386/Packages Hash Sum mismatch E: Some index files failed to download. They have been ignored, or old ones used instead.
