Title:
  release upgrader doesn't re-enable updates after failure

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

Bug description:
  If a release upgrade fails (my example is in a failure to calculate
  the upgrade: https://bugs.launchpad.net/bugs/1726180) the software
  sources are reset but updates are not re-enabled,   This has meant in
  my case going a month without updates, which introduces a security
  exposure to my system.

  In my case, the first two updates on the "Updates" tab of software
  sources should have been re-enabled (zesty-security and zesty-
  updates), but were not.

  Expected behaviour:  if the release upgrader cannot complete the
  upgrade, it should reinstate the software sources as they were prior
  to the upgrade.
