Got this message when I logged in and decided to upgrade. I am a noob. So anyways, I ran the command and next thing I know, I can no longer log into it after the reboot. What the heck happened?

I get ssh: connect to host port 22: Network is unreachable

New release 'oneiric' available. Run 'do-release-upgrade' to upgrade to it.

Sorry, I think it was just Ubuntu and not Linux Mint. – Scott Yu - Front-End UX May 10 '12 at 20:29

Remote ubuntu (Mint) becomes unreachable

Linux Mint is actually a derivative of Ubuntu; I don't think it allows you to do a do-release-upgrade the way Ubuntu does. So it's quite possible the upgrade to "Ubuntu" from "Mint" messed something up which.... (see below)

ssh: connect to host port 22: Network is unreachable

...left the remote computer unable to connect to the internet (which is exactly what this error means). Since it's not connected, the only way to troubleshoot this is if you (or someone else) can somehow access the Mint computer locally. Is there a way to do so?

Yes, I have the machine now. Lot of trouble getting hold of it. I should just have run ubuntu and forget Mint. Too much hassle. – Scott Yu - Front-End UX May 10 '12 at 20:13
Actually, if I remember correctly.. I think I did have Ubuntu and not Linux Mint... – Scott Yu - Front-End UX May 10 '12 at 20:28
Well, did you get it working now? – izx May 10 '12 at 21:56
I am just going to reformat everything. Don't want to mess with it anymore. Thank! – Scott Yu - Front-End UX May 11 '12 at 5:36

Reformatting was not necessary. The only fix was to contact your VPS support crew and have them rebuild GRUB for you, a simple task but requires on-site assistance.
