Syntax for sudo apt-key

I am trying to install zcash into my Ubuntu via Home · zcash/zcash Wiki · GitHub . I am stuck on the second step in adding the fingerprint and tried several variations. Please provide me the specific syntax.

wget -qO - | sudo apt-key add -

Also, the instructions contained under (User Guide under “from source” -I would put the link but I have a limit on 2 URLs per post) are actually different for debian distros than the link I provided above. Which is more accurate?

Hi, what error message did you receive on that command?

The instructions in “from source” guide are to build it locally rather than using the apt repo. They’re two different methods but apt is better because it makes for easier install and upgrades.
