[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 - 1.4ubuntu1

---------------
unattended-upgrades (1.4ubuntu1) cosmic; urgency=medium

  * Merge from Debian unstable
    - Remaining changes:
      - unattended-upgrades: Do not automatically upgrade the development
        release of Ubuntu unless Unattended-Upgrade::DevRelease is true.
    - Dropped changes, included in Debian:
      - Stop rewriting test apt.conf in test_untrusted.py.
      - Fix test_on_battery on Ubuntu development releases

unattended-upgrades (1.4) unstable; urgency=medium

  * Skip starting init.d script in debhelper-generated postinst part
    (LP: #1778800)
  * Use "deb-systemd-invoke start" instead of "systemctl start" in postinst.
    It is used only in a workaround applied for a Debian bug and for upgrading
    from pre-bionic versions.
  * Clear cache when autoremoval is invalid for a package set marked for
    removal (LP: #1779157)
  * Clear cache after failed commits to return from a possibly invalid state
  * Unlock for dpkg operations with apt_pkg.pkgsystem_unlock_inner() when it
    is available, also stop running when reacquiring the lock fails.
    Thanks to to Julian Andres Klode for original partial patch
  * Use fully qualified domain name in email subject.
  * Send email about all failures and crashes (Closes: #898607)
  * Add short textual summary of the results in the summary email
  * Recommend overriding configuration in a separate file.
    This can be better than changing /etc/apt/apt.conf.d/50unattended-upgrades
    because package updates don't conflict with local changes this way.
  * Adjust candidates only for packages to be possibly installed
    (Closes: #892028, #899366) (LP: #1396787)
  * Add Unattended-Upgrade::OnlyOnACPower config file example for all
    distributions
  * debian/control: Drop redundant Testsuite: autopkgtest field to keep Lintian
    happy
  * Bump Standards-Version to 4.1.4
  * 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.
  * Skip updates on metered connections (Closes: #855570)
  * Quote shell variables in autopkgtest
  * Stop u-u early when it should stop later anyway
  * Measure time for --dry-run and after all updates are installed in
    autopkgtests
  * Filter out packages cheaper when they are not from allowed origins
  * Collect autoremovable packages, too, when looking for upgradable ones
