The instructions are not up to date...Code:
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
The package software-properties-common incudes the apt-add-repository commamd.
Code:
sudo apt-add-repository ppa:<user>/<ppa-name>
If that doesn't work you will need to manually download the key, add it to the keyring, put it in /etc/apt/trusted.gpg.d/ and change the permissions and owner...
