I just came across this offer Extremetech which judging from Techdirt was around even earlier in 2016.
It doesn't have to be up to date, but given it was available in 2016 the content could be older.
Can anyone vouch for its quality, or know an alternative which is more up to date?
I've never heard of them. I'd recommend Linux Academy though. Mainly because they provide VMs for a hands on lab. They offer student discounts as well if you still have access to a .edu address.
