Moving to LUKS

Linux Mint was good, but they started to become a bad distro in the last years. They lack behind in every way. For example is Mint shipping an ancient version of XWayland. There is no VRR or HDR support. Cinnamon (the DE if Mint) is a cobbled-together DE out of GNOME and some applications are based of GNOME 38. The hardware drivers on Mint are compared to Ubuntu or Fedora pretty old and newer hardware has really bad support or does not work at all. Mint is based of Ubtuntu LTS which also explains a bit way the lack so much behind packages, but this also creates a security concern regarding kernel patches. Their AppArmor is enabled, but not really doing anything. But this is more an issue of general Linux. On Fedora you have SELinux that actually has an okay default config that does actually try to protect the user. Linux Mint tries to push users to Home-folder encryption instead of FDE, which in my eyes is a pretty big issue. Also, X11 is used by default in Mint through Cinnamon, which creates another security issue due the lack of isolation. Edit: There are other you can try like Ubuntu, SecureBlue (pretty hard for a beginner) or Fedora Atomic. But I would argue that Fedora is better and more modern than Ubuntu and SecureBlue is to hard for a beginner. So I see Fedora as a good middle ground for you.
