Comment 13 for bug 1822886

This bug was fixed in the package ubuntu-release-upgrader - 1:18.04.31

---------------
ubuntu-release-upgrader (1:18.04.31) bionic; urgency=medium

  * DistUpgradeController.py: Instead of checking every sources.list entry to
    see if they are accessible keep track of the uris and only test once per
    uri thereby preventing situations where entries for the same server are
    enabled and disabled. (LP: #1822886)
  * debian/control: build depend on the new version of update-manager which
    supports checking to see if an https url is downloadable. (LP: #1823410)
  * tests/test_sources.list.py: add a test for https support.
