I am following [https://docs.opennebula.org/5.6/deployment/opennebula\_installation/frontend\_installation.html](https://docs.opennebula.org/5.6/deployment/opennebula_installation/frontend_installation.html) and on step 6 I get this error:

Failed to start opennebula.service: Unit opennebula.service not found.

Also /var/log/one catalog does not exists

Ubuntu 17.10.

I went back and redid package installation and got error about missing libcurl3 after installing it I can start open nebula service easily.

I am pretty sure `apt-get install opennebula opennebula-sunstone opennebula-gate opennebula-flow` succeed before.

Did you try `systemctl unmask opennebula.service` ? One time it worked to me.

What worked for me was to rerun installing packages. Turned out one was missing but I am pretty sure installing packages succeeded before.
