Have 2 computers running linux Mint 17, the upgrade installed fine on the first one but the second one I am having problems with, Followed all the instructions and everything appeared to be downloading ok but then the message .........Failed to fetch http://packages. Could not connect to packages linuxmint com:80 (126.96.36.199) connection timed out. Upgrade not successful. Anyone any ideas ? NB: Managed to upgrade successfully at the third attempt !
