I tried updating to Ubuntu 14.04 today, but Software Updater seems to be having some issues. First of all, I get the following message while the updater is preparing the update:
Third party sources disabled
Some third party entries in your sources.list were disabled. You can re-enable them after the upgrade with the 'software-properties' tool or your package manager.
I'm not sure if this is an issue, but it seems suspicious. Then, when the updater moves on to setting new software channels, the entire process stops and I get this message:
W:Failed to fetch gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_trusty_universe_source_Sources Hash Sum mismatch , W:Failed to fetch gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_trusty_main_binary-amd64_Packages Hash Sum mismatch , W:Failed to fetch gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_trusty_universe_binary-i386_Packages Hash Sum mismatch , W:Failed to fetch http://archive.canonical.com/dists/trusty/Release Unable to find expected entry 'parter/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file) , E:Some index files failed to download. They have been ignored, or old ones used instead.
I would like to update to 14.04 and this is preventing my update. Help would be greatly appreciated.
