I try to configure unattended upgrades with systemd timer as explained here
/etc/systemd/system/apt-daily-upgrade.timer.d/override.conf file like that :
[Unit] Description=Daily apt upgrade and clean activities After=apt-daily.timer [Timer] OnCalendar=Mon,Wed,Fri 6:00 RandomizedDelaySec=60m Persistent=true [Install] WantedBy=timers.target
When I check when will be next trigger I get :
# systemctl status apt-daily-upgrade.timer ● apt-daily-upgrade.timer - Daily apt upgrade and clean activities Loaded: loaded (/lib/systemd/system/apt-daily-upgrade.timer; enabled; vendor preset: enabled) Drop-In: /etc/systemd/system/apt-daily-upgrade.timer.d └─override.conf Active: active (waiting) since Wed 2020-03-11 13:23:17 UTC; 53min ago Trigger: Thu 2020-03-12 06:31:32 UTC; 16h left
So it supposes to be triggered next thursday while Thus is not definied in OnCalendar parameter.
Don't see what I miss :/
