Hi I’m trying to install Open edx followin the Native Installation guide.

I try to install several times with the same result:

Hi César,

This kind of error can happen when you are trying to use apt while another user is doing too or if the user who is currently running the sudo command doesn’t have enough rights to do so (like running apt).

Since other playbooks are already running apt commands successfully, like mongodb-3.2 playbook, are you sure that no other apt processes are running in the background?

Hi Geoffrey, I really don’t know if other apt process is running, I will run the install process again and follow it with htop to ensure no other apt process is running.

I ran the installation process with the root user and the process fails at the rbenv installation.

The second try I use a non sudoer user and the process fails at the installation of the demo course.

TASK [demo : import demo course] ***********************************************
fatal: [localhost]: FAILED! =>
