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

[Haw Loeung]

We're still seeing regular request spikes to changelogs.ubuntu.com. Can
we move release-upgrade-motd, the bit that downloads and checks for a
new Ubuntu release to systemd timer units instead?

/usr/lib/ubuntu-release-upgrader/release-upgrade-motd which calls
/usr/lib/ubuntu-release-upgrader/check-new-release which uses
MetaReleaseCore from UpdateManager.Core.MetaRelease

** Also affects: ubuntu-release-upgrader (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: ubuntu-release-upgrader (Ubuntu)
       Status: New => Confirmed

  update-notifier-common weekly cron job runs at the same time for all
  computers across the globe

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed
Status in update-notifier package in Ubuntu:
  Confirmed

Bug 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
