[Bug 1779157] Re: /usr/bin/unattended-upgrade:AssertionError:/usr/bin/unattended-upgrade at 1927:main:do_install

[Launchpad Bug Tracker]

This bug was fixed in the package unattended-upgrades -
1.1ubuntu1.18.04.4

---------------
unattended-upgrades (1.1ubuntu1.18.04.4) bionic; urgency=medium

  * Redirect stderr output in upgrade-between-snapshots, too, otherwise it
    breaks the test sometimes (LP: #1781446)

unattended-upgrades (1.1ubuntu1.18.04.3) bionic; urgency=medium

  * Redirect stderr output in upgrade-all-security, otherwise it breaks the
    test (LP: #1781446)

unattended-upgrades (1.1ubuntu1.18.04.2) bionic; urgency=medium

  [ Balint Reczey ]
  * Clear cache when autoremoval is invalid for a package set marked for
    removal and clear cache after failed commits to return from a possibly
    invalid state (LP: #1779157)
  * Don't start or gracefully stop upgrade on battery (LP: #1773033)
  * Skip updates on metered connections (Closes: #855570) (LP: #1781183)
  * Add debian/tests/upgrade-all-security to install all current security updates.
    On development releases this tests latest stable, on stable releases it tests
    the release itself.
  * Speed up unattended-upgrade (Closes: #892028, #899366) (LP: #1396787)
    - Adjust candidates only for packages to be possibly installed
    - Filter out packages cheaper when they are not from allowed origins
    - Collect autoremovable packages, too, when looking for upgradable ones
    - Measure time of running with --dry-run in autopkgtests
  * Skip starting init.d script in debhelper-generated postinst part
    (LP: #1778800)

  [ Ivan Kurnosov ]
  * Fixed is_pkgname_in_blacklist to be side-effect free. (LP: #1781176)
    Otherwise 'is_pkgname_in_blacklist' mutates the 'pkgs_kept_back' and
    'unattended-upgrades' treats the package as a blacklisted candidate
