[Bug 1836475] Re: [SRU] update-notifier-common weekly cron job runs at the same time for all computers across the globe

[Timo Aaltonen]

Hello Junien, or anyone else affected,

Accepted update-notifier into focal-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
notifier/3.192.30.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: update-notifier (Ubuntu Focal)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-focal

Title:
  [SRU] update-notifier-common weekly cron job runs at the same time for
  all computers across the globe

Status in update-notifier package in Ubuntu:
  Fix Released
Status in update-notifier source package in Focal:
  Fix Committed
Status in update-notifier source package in Groovy:
  Fix Released

Bug description:
  [Impact]

  * The fix spreads access to changelogs.ubuntu.com over a full week (it was decided this was preferable to the 24h originally requested)
  * This results in reduced load on Canonical's infrastructure, of benefit to all users

  [Test Case]

  On Focal desktop and server installations:

  * sudo add-apt-repository ppa:waveform/update-notifier
  * sudo apt update
  * sudo apt install update-notifier-common
  * Ensure that /etc/cron.daily/update-notifier-common and /etc/cron.weekly/update-notifier-common have been removed
  * Ensure systemctl status update-notifier-motd.timer shows a valid timer
  * Ensure systemctl status update-notifier-download.timer shows a valid timer

  [Regression Potential]

  Low; the patch is already in active use in Groovy.

  [Original Description]

  Hi,

  /etc/cron.weekly/update-notifier-common is run at the same time on all
  machines across the globe. It's putting unnecessary stress on
  Canonical's infrastructure (changelogs.ubuntu.com, specifically).
  Could we please have this job spread out over 24h ?

  And could we please SRU this change ?

  Thanks
