First time i ever see this, i am used to PBIS-Open ! 
wget -O - https://repo.pbis.beyondtrust.com/apt/RPM-GPG-KEY-pbis sudo apt-key add -
sudo wget -O /etc/apt/sources.list.d/pbiso.list https://repo.pbis.beyondtrust.com/apt/pbiso.list
sudo apt-get update
sudo apt-get install pbis-open
- Restart.
Check if your domain is reachable
nslookup yourdomain.local
something like this…
sudo domainjoin-cli join --disable ssh yourdomain domainadmin@yourdomain
- At first your sudo pass
- Then your domain admin pass
- Restart
