Package: unattended-upgrades Version: 2.8 Severity: wishlist When unattended-upgrades is run with the --dry-run flag, it still acquires a cache lock (presumably from apt update?), and makes a pid file. These can interfere with unattended-upgrade runs that are done without the --dry-run, and can result in Cache acquire lock errors.
Ideally, for --dry-run, unattended-upgrades could use a temporary directory for the lists location, and the pid, if it even needs one. thanks! -- System Information: Debian Release: 11.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable-debug'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-11-amd64 (SMP w/8 CPU threads) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages unattended-upgrades depends on: ii debconf [debconf-2.0] 1.5.77 ii lsb-base 11.1.0 ii lsb-release 11.1.0 ii python3 3.9.2-3 ii python3-apt 2.2.1 ii python3-dbus 1.2.16-5 ii python3-distro-info 1.0 ii ucf 3.0043 ii xz-utils 5.2.5-2 Versions of packages unattended-upgrades recommends: ii anacron 2.3-30 ii cron [cron-daemon] 3.0pl1-137 ii systemd-sysv 247.3-6 Versions of packages unattended-upgrades suggests: ii bsd-mailx 8.1.2-0.20180807cvs-2 ii needrestart 3.5-4 ii postfix [mail-transport-agent] 3.5.6-1+b1 ii powermgmt-base 1.36 ii python3-gi 3.38.0-2 -- debconf information excluded
