My default setting in "System Settings" > "Software & Updates" > "Ubuntu Software" > "Download from" is "Server for Germany" (de.archive.ubuntu.com). Updating apt I got:
W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/trusty-updates/universe/i18n/Translation-en Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old ones used instead.
So I tried servers like "Main server" (archive.ubuntu.com) or "Server for United States" (us.archive.ubuntu.com) and everything went fine.
