Bug Description

0) Machine

Raspberry Pi 4 Model B Rev 1.1

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

Description: Ubuntu 19.10
Release: 19.10

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

3) What you expected to happen

Successful upgrade to Ubuntu 20.04.

4) What happened instead

Failed upgrade. 404 error for those URLs:

http://security.ubuntu.com/ubuntu/dists/focal-security/main/binary-arm64/Packages
http://us.archive.ubuntu.com/ubuntu/dists/focal/main/binary-arm64/
http://us.archive.ubuntu.com/ubuntu/dists/focal/main/binary-arm64/Packages

5) Resolution

It appeared that the selected servers did not contain the arm64 architecture. It should have used ports.ubuntu.com.

Modifying the upgrader to select ports.ubuntu.com for the architecture arm64 solved the issue. (see patch attached)

Thanks for bringing this issue up and working on a patch for it. I've actually modified the arch check to drop powerpc and sparc, and to add every architecture which is on ports.ubuntu.com.

Out of curiosity how did you end up with the sources.list entries which 404'ed?

You are welcome. I wasn't sure indeed if it was the right fix, but it did the job for my upgrade. If you have a link to it, I would be interested to check your modification also for my own curiosity.

About your question, the upgrader complained about the 404 errors on the console logs. I copied them from there and figured out that something was wrong regarding the choice of the server. Is this what you were wondering?

Here's the modification I made:

I'm curious about how those entries ended up in your sources.list file. The installer uses ports.ubuntu.com urls.

I think a better approach that avoids duplicating which archs are where and the urls is to talk to aptsources and get the BaseURI, but I'm not sure how :D

Right, my sources.list had originally ports.ubuntu.com urls. Since I was still with the 19.10 version, I couldn't update my system anymore. To update it, I changed the urls to old-releases.ubuntu.com/ubuntu/ and then did the upgrade. It is probably why I ended up having this bug ...
