I am about to set up a cloud instance with linux operating system, and the common choice here normally would be ubuntu. But since they failed their newest release, and I have the option of going fedora or debian. What would you guys recommend for server?


I would use Ubuntu LTS (free) or Redhat Enterprise Linux. If paying is not an option, some RHEL derivate would probably also work.
Care to elaborate how Ubuntu failed newest release?
yea, ubuntu ‘failing’ is news to me, too. their infrastructure has been hammered by bad actors, and pre-release daily spins were at-times a bit rocky, but the release itself (barring a few potential issues on the desktop with all the changes) seems to be solid.
