I'm running the Ubuntu 20.04.02 (Focal) version and its production environment. Planning to apply the latest OS patches to these servers. Kindly suggest, that we roll back all upgrades and back to the earliest.
Example: Centos or Redhat, we have options like "yum history undo ". Do we have the same option in Ubuntu?
I don't want to downgrade each package one by one. Because since we are in production, any impact they ask us to roll back all recent changes. Kindly suggest.
