Ubuntu only does security updates, no? So that seems like a bad idea.
If you still want to do that, I guess you’d probably need to run your own package mirror, update that on Monday, and then point all the machines to use that in the sources.list and run unattended-upgrades on different days of the week.
Yeah no the other poster is correct, I meant Ubuntu doesn’t do feature updates after release. You seem worried about something that’s quite unlikely to happen (breakage introduced from minimal patches), while delaying security fixes. And I assume the vast majority of updates are security fixes.
And I also think you’re being rude in this whole thread.
