Problemls adding the zulu apt key


i did install openhab but got a error at the end, so reading more carefull i found out java is not installed

so i wen’t there and went to
“Installation on Linux using an APT Repository”

followed this steps

“Complete the steps in Attach the APT Repository on an Ubuntu or Debian System.”

and the comand

apt-key adv --keyserver hkp:// --recv-keys 0xB1998361219BD9C9

make a error like this

Executing: /tmp/apt-key-gpghome.9XjyMIvLw6/ --keyserver hkp:// --recv-keys 0xB1998361219BD9C9
gpg: failed to start the dirmngr ‘/usr/bin/dirmngr’: Datei oder Verzeichnis nicht gefunden
gpg: connecting dirmngr at ‘/run/user/0/gnupg/d.otrbypgocjs9zr6msni9rs57/S.dirmngr’ failed: Datei oder Verzeichnis nicht gefunden

@sihui, perfect feedback, thanks a lot and by surprise it is possible to install java at the end too
