Important step after installation succeeded. [source](https://helpcenter.veeam.com/docs/backup/vsphere/hardened_repository_ubuntu_install.html?ver=120)

> By default, the user account you created during the installation is the member of the sudo group and has enough privileges to deploy and install required Veeam Backup & Replication components. In that case, when you add a Linux server as a hardened repository to the backup infrastructure and specify single-use credentials, you do not need to enter the password for the root account. After the repository is added, you must remove the user account from the sudo group to make it a non-root account. To do this, perform the following steps:
> 
> a. Allow the user account to reboot and shutdown the operating system:
> 
> `sudo bash -c "echo 'user1 ALL = (root) NOEXEC: /usr/sbin/reboot' >> /etc/sudoers"`
> 
> `sudo bash -c "echo 'user1 ALL = (root) NOEXEC: /usr/sbin/shutdown' >> /etc/sudoers"`
> 
> b. Remove the user account from the sudo group:
> 
> `sudo deluser user1 sudo`
> 
> Note that the next time you log in with this user account, it will lose sudo permissions. if you need to execute commands as a privileged user, you must boot the operating system into the single user mode.
