Our school is wanting to switch from a mix of Windows 8 laptops and Chrome OS laptops to all running Ubuntu 20.04, we got a few working and running as a test and there running amazing, what we were wondering was if we needed any special licensing as we did with the others or if we were good to go with just installing Ubuntu on the rest of them?
From https://ubuntu.com/desktop
From https://ubuntu.com/licensing:
Anybody, including you and your organization, can freely install Ubuntu as much as you like without purchasing any licenses, ever.
An enterprise-wide roll-out of Ubuntu may look different from a roll-out of chromebooks or Windows laptops: Hardware incompatibility, Admin access, and enterprise infrastructure can be quite different from a Windows or Chrome environment. Test, test, test because students and other users will find your weak spots!
