[Touch-packages] [Bug 1824088] Re: unattended upgrade ran one day after schedule
Awesome work Magnus. Well done! Since the bug is related to APT, is Debian then considered the upstream of this source? Would it be appropriate to also file a bug in their bug tracker? If so, I can arrange that. -- 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: Confirmed Bug description: I have noticed a strange behaviour in unattended upgrades.

How about this idea? What if we add this line to the beginning of usr/lib/apt/apt.systemd.daily: export TZ="UTC0" (I got this idea from the GNU Coreutils manual.

[Touch-packages] [Bug 1824088] Re: unattended upgrade ran one day after schedule
If we look at lines 131 and 132 in /usr/lib/apt/apt.systemd.daily, we
will se the following:
interval="${interval%d}"
interval=$((interval*60*60*24))
I’m not 100% certain but I think that this time logic is what cause the
bug to occur, in accordance with what Magnus has pointed out in his
comments.
(It’s possible that lines 122-130 are also relevant.)
Any ideas on how to modify the code in order to avoid this bug?
