Hello everyone!

I’m trying to install OpenNebula Forntend on Ubuntu server 18.04. I followed instructions  
in the guide: first added opennebula repositories, second install packages from repositories and unexpectedly crashed. Messages like “broken packages”, “unmet dependencies” appeared on my command line.

Check the output from apt update. Perhaps you are having some issues with some of your repositories. Also, only to be sure, check “apt-cache policy opennebula” to see the OpenNebula version that is going to be installed.

Exactly, it was a repository issue. I tried to install same packages on Ubuntu 18.10 and all was fine. However, I preferred to install it on a LTS version, such as 18.04.  
I don´t know why, but it seems that something is missing in **/etc/apt/sources.list** file, so I modified it and everything worked.

That is my **sources.list** content:

> deb [Index of /ubuntu](http://archive.ubuntu.com/ubuntu) bionic main restricted universe multiverse  
> deb [Index of /ubuntu](http://archive.ubuntu.com/ubuntu) bionic-security main restricted universe multiverse  
> deb [Index of /ubuntu](http://archive.ubuntu.com/ubuntu) bionic-updates main restricted universe multiverse  
> deb [Index of /ubuntu](http://archive.ubuntu.com/ubuntu) bionic-backports main restricted universe multiverse
