Pretty straightforward from here:
wget -qO – https://package.perforce.com/perforce.pubkey | sudo apt-key add –
….. then add the following line to that file
deb http://package.perforce.com/apt/ubuntu xenial release
apt-get install helix-p4d -y
… in the step where you choose the port, “ssl:1666” means it sets up ssl, which means *everything* has to use ssl configs, which is another layer of complexity. Handy, yes, but more complex.
After that, you can log in with any p4 client. It’s pretty good. You’ll have a new user – perforce – that runs the server, and things are generally in good shape.
