Upgrading a Raspberry Pi from a deprecated version?

se flag
Tom

I've got a raspberry pi that's running 19.10. On trying to install a new package today, I discovered that this version is deprecated. How can I upgrade this to 20.04 LTS?

I've tried changing the ports.ubuntu.com URLs in sources.list to old-releases.ubuntu.com but this doesn't seem to change anything. apt update says this:

root@otter:/etc/apt# apt update
Ign:1 http://old-releases.ubuntu.com/ubuntu-ports eoan InRelease

apt-get dist-upgrade fails with lots of HTTP 404s. do-release-upgrade appears to be doing... something... again, a lot of 404s and eventually it aborts with this:

404 Not Found [IP: 91.189.91.39 80], E:Some index files failed to 
download. They have been ignored, or old ones used instead.

Is there an upgrade path here? Or am I looking at blowing it all away and starting again? Really hoping not...

You do not upgrade in place for 19.10 to 20.04 LTS you make live media and do an install.

@Bobo - done. Changing `ports.ubuntu.com/ubuntu-ports` to `old-releases.ubuntu.com/ubuntu` does seem to get me a successful `apt update` so here's hoping the release upgrade also works.

@David - really??? The upgrade path from one version of Ubuntu to the next is to blow it all away and start again??? If that's true, it's rubbish. This isn't a mission-critical device, but it is where I run my work-from-home mirror of a private software repository. I really don't fancy downloading all 600GB of it again over the crappy VPN (which is why I mirrored it in the first place...)

You are not going from one to another as an upgrade. An upgrade would be 19.04 to 19.10 or 18.04 LTS to 20.04 LTS you want to jump to a different path hence re install.

Why would you lose the 600 GB of data? You of course make a back up first no matter how the new version was being installed. Upgrade or new. You will be offered to replace the existing OS. In MOST cases that does not affect the data.

@David suggest you read the question before commenting. I'm upgrading from 19.10 to 20.04 - they are consecutive versions. Or are you suggesting it is never possible to upgrade from a non-LTS version to an LTS version? If so, dear God, why?

@Bobo - still no joy running `do-release-upgrade`. 404s on URLs such as this: http://archive.ubuntu.com/ubuntu/dists/focal-security/main/binary-arm64/Packages

You missed the window for an online upgrade which is usually up to 3 months after the current release gets EoL status. In your case it ended around July 2020 or before. So, yes, install from scratch, period.

I got to it. Reinstalled from scratch. It does seem to be the only option. Thankfully, I'd put /opt and /home on separate partitions.

Whoever associated this with another question - no, they are more or less completely unrelated.

@Tom did you get his figured out? I'm in the exact same situation. Kind of a pain to install from scratch...

It seems that installing from scratch is your only option. I'll get to it any day now...

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.
