Package: unattended-upgrades Version: 1.11.2 Severity: normal Dear Maintainer,
* What led up to the situation? Trying to run unattended-upgrades does not result in upgraded packages (neither when done automatically nor manually) Running it manually with "unattended-upgrades -d" ends with following lines: Packages that will be upgraded: apt apt-utils base-files ca-certificates distro-info-data file grub-common grub-pc grub-pc-bin grub2-common iproute2 libapt-inst2.0 libapt-pkg5.0 libefiboot1 libefivar1 libgnutls30 libjpeg62-turbo libldap-2.4-2 libldap-common libmagic-mgc libmagic1 libp11-kit0 libpq5 libsqlite3-0 libssl-dev libssl1.1 libsystemd0 libudev1 libxml2 libzstd1 linux-image-amd64 linux-libc-dev openssl postgresql-11 postgresql-client-11 python-apt-common python-lxml python3-apt sudo tcpdump tzdata udev unzip Writing dpkg log to /var/log/unattended-upgrades/unattended-upgrades-dpkg.log Exception: 'NoneType' object has no attribute 'dependencies' InstCount=0 DelCount=0 BrokenCount=0 Extracting content from /var/log/unattended-upgrades/unattended-upgrades-dpkg.log since 2021-02-11 23:06:20 However it does not upgrade packages, and /var/log/unattended-upgrades/unattended-upgrades-dpkg.log remains zero-byte sized. * What exactly did you do (or not do) that was effective (or ineffective)? I seem to recall it working back in Stretch... I've tried running it manually and automatically for few weeks. I've also tried purging and reinstalling unattended-upgrades, as well as changing Unattended-Upgrade::MinimalSteps to "false" and to "true" - none of that helps. * What was the outcome of this action? I expected unattended-upgrades to automatically upgrade packages. * What outcome did you expect instead? Instead it dies with "Exception: 'NoneType' object has no attribute 'dependencies'" without upgrading packages. *** End of the template - remove these template lines *** -- System Information: Debian Release: 10.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-12-amd64 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages unattended-upgrades depends on: ii debconf [debconf-2.0] 1.5.71 ii lsb-base 10.2019051400 ii lsb-release 10.2019051400 ii python3 3.7.3-1 ii python3-apt 1.8.4.1 ii python3-dbus 1.2.8-3 ii python3-distro-info 0.21 ii ucf 3.0038+nmu1 ii xz-utils 5.2.4-1 Versions of packages unattended-upgrades recommends: ii cron [cron-daemon] 3.0pl1-134+deb10u1 Versions of packages unattended-upgrades suggests: ii bsd-mailx 8.1.2-0.20180807cvs-1 ii needrestart 3.4-5 ii nullmailer [mail-transport-agent] 1:2.2-3 ii powermgmt-base 1.34 ii python3-gi 3.30.4-1 -- debconf information: * unattended-upgrades/enable_auto_updates: true
