The Linux onboard ramp is as shallow as it has ever been. Just pick up a usb stick, shove a Linux distro on it and boot it on your PC or on an older machine you don't use anymore. Use it to do what you do usually. Things will be different. Resist the urge to shove random software from the net in it to solve problems. This is not windows. Don't reinstall even if you fuck up your system (and you will, multiple times). Ask questions and fix it yourself. Learn. Level up. Use the huge software repositories that are built in the system. Use flatpaks for the other stuff. Persist. Things will eventually click. One day you will feel at home. Then you have won.
