[Touch-packages] [Bug 1824088] Re: unattended upgrade ran one day after schedule
The thing is that it's only the delta that is handled in UTC not the iso-8601-part so it will work just fine. My first idé was to fix the interval calculations must like yours. The workaround for us was to set interval to always. We have local mirrors that can handle the load just fine even if we do updates every hour. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1824088 Title: unattended upgrade ran one day after schedule Status in apt package in Ubuntu: Triaged Bug description: I have noticed a strange behaviour in unattended upgrades.

[Touch-packages] [Bug 1824088] Re: unattended upgrade ran one day after schedule
The interesting about the code is that it always only treat the timestamp of the file as "-MM-DD" and nothing else (this also includes "now"). The code has functions for allowing the interval to be set down to 1s but is does not mean anything to the outcome of the script as it always looks for complete day(s). I can only guess that the code might have has some old reference where the script (or an other script) did something else. As of the output of "date +%s" it is dependent of the timezone when used with the --date command. It kind of looks like the "date" is inputed in the local timezone rather witch will make epoch time drift dependent of TZ. # Bionic $ TZ=UTC0 date --date="2020-01-01" +%s 1577836800 $ TZ=CET date --date="2020-01-01" +%s 1577833200 Using "date -u" will also fix this behaviour of date. $ TZ=UTC date -u --date="2020-01-01" +%s 1577836800 $ TZ=CET date -u --date="2020-01-01" +%s 1577836800 An easy fix for the original problem would be add the "-u" option to the date commands in the script: stamp=$(date -u --date="$(date -r "$stamp_file" --iso-8601)" +%s 2>/dev/null) now=$(date -u --date="$(date --iso-8601)" +%s 2>/dev/null) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1824088 Title: unattended upgrade ran one day after schedule Status in apt package in Ubuntu: Triaged Bug description: I have noticed a strange behaviour in unattended upgrades.

Setting TZ for the complete script will not work as it will make strange behaviour if you are far away from UTC/GMT TZ. You can set it for just the date command that returns the epoch time.

[Touch-packages] [Bug 1824088] Re: unattended upgrade ran one day after schedule
This IS related to daylight saving. The script: /usr/lib/apt/apt.systemd.daily check that the script is not run twice at the same period. The script checks the date of today and the date of the last timestamp to determine the the diff. The interval is calculated using the number of seconds per day multiplied by number of days. If a day in the interval has less then 24h this check fails. This also affects the apt-daily.service that updates.
