Bug description:
  [Impact]

   * Flaky upgrade-between-snapshots autopkgtest prevents developers to
  use the test efficiently.

  [Test Case]

   * Run autopkgtests, observe the upgrade-between-snapshots test
  passing or failing but being marked as FLAKY.

  [Regression Potential]

   * None, the test was failing often due to connectivity/internal
  errors of snapshot.debian.org.

  [Other Info]

   * The whole autopkgtest is marked to be failing on amd64 to mitigate
  the single flaky test, this marking can be removed after marking this
  single flaky test.
