what is Ubuntu 20.04 LTS price or its free until 2025.?
Ubuntu is free … after the 5 year period you can buy extended security maintenance (i.e. because your company can not migrate off 20.04, you have application software that requires the old stuff etc) or move on to 24.04
It’s always free and everything available publically.
For additional optional features, Ubuntu Advantage may be required. However, that too is free for individuals. So for 10 years of free support until 2030 one may need to enroll with Ubuntu Advantage Personal.
That is generous - Had no idea it was free for individuals!
