  E: Some index files failed to download. They have been ignored, or old ones used instead.

  $ apt-get -v
  apt 1.6.12ubuntu0.1 (amd64)

  Also, Software Updater (version 1:18.04.11.12) after hitting "Install" gives pop-up:
  "Requires installation of untrusted packages
   This requires installing packages from unauthenticated sources."
  Only options: "Settings..." and "OK"
  And it is not OK; I have not configured any unauthenticated sources!

  This occurs when enabling updates from Ubuntu Base (but not Security
  updates).

  I expected to not get such errors and updating to occur normally.

  $ lsb_release -rd
