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?


My first choice would still be Ubuntu, however if you don’t like them RHEL is available for free for homelab’s by jumping through some hoops.
Might also take a look at NixOS. Been running it for a while with no issues.
I believe Rocky Linux is also a free clone of RHEL.
