during installtion, an error occured when i run a command sudo su - bench To run a command as administrator (user “root”), use “sudo ”.
See “man sudo_root” for details.
Hi Rakesh1
ok yes this prompt ‘root@root-VirtualBox’ means currently you are (already) in the root user account.
So for root to access the user account ‘bench’ no need to use sudo instead just run this:
root@root-VirtualBox:~$ su - bench
I assume in this context ‘bench’ refers to a user and not a command - please share a link to your install instructions, that would help give context here to what you wish to do from what install step you are at.
