A couple of dedicated Linux-enthusiasts provide this (not-for-commercial-use) among other mapping services, so they can alt-OS while they alt-OS.

I loved using OS 1:50,000 maps and had the whole country downloaded via Limewire in the day. But now I realise that they are pretty shit for most things as I've got used to the far greater resolution of Google maps and the like - I'm a big fan of organicmaps.app/
