Title:
  ports.ubuntu.com not selected for arm64 architecture

Status in ubuntu-release-upgrader package in Ubuntu:
  New

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)
