Ubuntu 12.04 to 14.04 Upgrade
I have an Ubuntu 12.04 LTS droplet, and I'd like to upgrade to Ubuntu 14.04 LTS. If I run 'do-release-upgrade', it returns no new releases, whereas running 'do-release-upgrade -d' will correctly get the new release. If I continue after doing the latter command, it says "no valid mirror found", and I don't want to update the sources.list file to 'trusty' in case the DO mirror isn't there. If this is a known thing and I should just say yes anyway, then I'll go ahead and do it, I'd just like to know whether doing this upgrade is going to ruin my droplet! Any help greatly appreciated, as I've not been able to find an answer anywhere so far.
