Question I've just managed to get Linux to work on my Chromebook, how do I download the Linux flavour of this

Above.

Can someone give me a link to download the DEB to install the latest version of the Hub please?

 

Make with the helpful comments please? I am aware of Google.

 

Didn't work.

I followed the instructions to the letter

Using Linux Debian on Chromebook!

 

No you didn't. Literally.

 

You have a lot of typos in your console.
Do not try to type it on your own.
Copy and paste it from this page: https://docs.unity3d.com/hub/manual/InstallHub.html#install-hub-linux

At least it is "apt-key add -", NOT "apt - key add -".
But your console already told you. Try to understand, what console-messages are trying to tell you.
Console is very pedantic.

 

Lol, and I thought I was a Grammar Nazi

 

I tried to copy and paste the code in the Linux terminal, it didn't work.

 

Can you send some screenshots?

 

Later.
