Ubuntu server upgrade

us flag

I have couple of very old Ubuntu servers running that I HAVE to upgrade, I cannot install new machine. Old as in 12.04 LTS version old. I did try new install of 12.04 and upgrade that to 14.04 and all the way to 22.04 and it works. I just do not find any information about how long I will be able to upgrade 12.04 to newer versions.

Does this answer your question? [How to install software or upgrade from an old unsupported release?](https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release)

Please note that however you go about this, it's totally unsupported, since it was never meant to upgrade from such old releases.

Ubuntu 12.04 LTS upgraded to 14.04, which is already *end of standard support*. Ubuntu 12.04 ESM is no longer supported, and its upgrade path to 14.04 ESM has ended too I believe, but ESM support isn't on-topic on this site anyway

@ArturMeinild this will come handly when regular "do-release-upgrade" does not function anymore. I need the date until it will function without needing to manually alter sources.list

there is no date except it mentions the word **after** EOL; where the release team modify https://changelogs.ubuntu.com/meta-release and the *Supported: 1* is changed to *Supported: 0* and the [Ubuntu-release-upgrader](https://launchpad.net/ubuntu/+source/ubuntu-release-upgrader) tool will no longer allow upgrade. (*historically this has ranged from hours **after** to many months after; though looking at whats in queues in the days before EOL is probably your best bet at predicting*)

^ my *months* is incorrect... the *Ubuntu Release Team* have a list of tasks to perform, and the *months* relates to later steps in their procedures... the modification of that file is early on that list, thus *weeks* (if not *day(s)*) maybe more accurate for the modification of that file (compared to my *months*) sorry (*months* being all tasks when a release reaches EOL)

There is an english expression for this: "Living on borrowed time." You **already** should not be able to release-upgrade Ubuntu 12.04. You are very fortunate that you can.

@guiverc Thanks for the meta-release link. OK, since 14.04 has "Supported: 1" I was able to upgrade to it and 14.04 is supported until April 2024 (https://wiki.ubuntu.com/Releases) so I should be able to upgrade to 14.04 at least until April 2024?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
