It has been fixed by applying this modification in sudoers

oneadmin ALL=(ALL) NOPASSWD: ALL

This does not convince me at all since we grant total permissions to the oneadmin user, how could we configure it in the most optimal way?

Versions of the related components and OS (frontend, hypervisors, VMs):
1 Front-End (ubuntu 18.04)
3 Nodes hypervisors (ubuntu 18.04)

The package opennebula-common should have this set up for you. This should be the content of /etc/sudoers.d/opennebula on 5.8.1
