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

[Launchpad Bug Tracker]

[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
