I discovered the hard way that if you want to use a VPN [virtual private network], and you should, it’s important to find out if a particular VPN will work with the distro you have selected.
For example I use ProtonVPN and chose AntiX distro for an older laptop. Come to find out Proton requires the distro’s init software to be systemd which AntiX’s is not.
You can find out about the init software for your distro at https://distrowatch.com/ under the “Feature” section.
