I happen to be running Ubuntu 12.10 on my machine and I noticed that it is no longer supported since there are no quantal repositories left and I can't update or install any software any more.
I tried to run update-manager, but it failed to download repository information since it doesn't exist any more.
How would I proceed to upgrade this machine (without a complete new install of course)?
This question was addressed a couple times, the relevant links are
How to install software or upgrade from an old unsupported release?
Can I skip over releases when upgrading?
Both of them suggest that it's probably a mess to upgrade from 12.10 to 14.04 since it would involve 3 upgrades, so it might be easiest to change archive.ubuntu.com to old-releases.ubuntu.com (as in the top answer in the first link) and do a fresh install when I have the time.
