I don't know if it works differently in the US but the best way to build your credit score is to not take on debt.
Keeping your credit utilization low and not missing any payments is the key. It's an indication of how likely you are to meet the payments.
If you max your credit cards out and just pay the minimum amount, carrying thousands of dollars of debt and as a result can't get a mortgage or a car loan because your credit score is shit then the system is working as expected.
Depends on what you're using it for. Fedora's release ver upgrades are fairly seamless. Just a big dnf update really.
Meanwhile I have a bunch of servers stuck on CentOS 7 that are going to need to be completely rebuilt by next summer. I'm also limited by them because the pdf generator I use requires a version of libpango that was released in 2019 and EL7 is stuck on the 2018 version.
I switched from Rocky to Fedora Server because I was sick of running into compatibility issues with dependencies that exist in the Fedora repo and not EL.
Specifically postgres. One of the projects requires postgis and gdal, which are in the Fedora community repo, but I have to use the official postgres repo on Rocky and the people that maintain those repos are literally incompetent. They have an automated script that generates all of the packages and they can't even be bothered to double check that the packages are built against the correct version of postgres, so your install will fail because a PG14 package is looking for a dependency that only exists in the PG11, PG12, and PG15 repo.
