Package: unattended-upgrades Version: 1.1 Severity: normal Dear Maintainer,
When unattended upgrade runs it is using up 100% CPU for half an hour: top - 12:19:08 up 7 days, 21:32, 1 user, load average: 1,21, 1,33, 1,28 Tasks: 242 total, 2 running, 180 sleeping, 0 stopped, 0 zombie %Cpu(s): 28,0 us, 7,9 sy, 0,0 ni, 63,6 id, 0,1 wa, 0,0 hi, 0,3 si, 0,0 st KiB Mem : 16305448 total, 2055960 free, 8917952 used, 5331536 buff/cache KiB Swap: 19956732 total, 19762884 free, 193848 used. 4859524 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30106 root 20 0 187660 117692 60896 R 100,0 0,7 42:28.55 unattended- upgr I see no reason why it is eating up so many system resources, especially because this is only the control process it is not even downloading/unpacking/installing anything on its own, except pooly designed algorythms. This behaviour is especially bad on battery powered devices. regards Hans -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.14.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages unattended-upgrades depends on: ii debconf [debconf-2.0] 1.5.66 ii lsb-base 9.20170808 ii lsb-release 9.20170808 ii python3 3.6.4-1 ii python3-apt 1.4.0~beta3+b1 ii ucf 3.0038 ii xz-utils 5.2.2-1.3 Versions of packages unattended-upgrades recommends: ii anacron 2.3-24 ii cron [cron-daemon] 3.0pl1-130 Versions of packages unattended-upgrades suggests: ii bsd-mailx 8.1.2-0.20160123cvs-4 pn needrestart <none> ii ssmtp [mail-transport-agent] 2.64-8+b2 -- debconf information excluded
