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

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