I have installed Ubunto on VirtualBox and I don't have permissions to do anything. I have reinstalled it twice and it seems the fresh installation does not provide my user with permissions.
I tried installing Nodejs using sudo apt-get install -y nodejs and did manage someone to install it, then tried installing some package in node and had no permissions of doing so.
I reinstalled and tried installing Node with files from the official website and move them into /usr/ directory(?) and had no permissions of doing so.
Any solution online that I found with sudo command ends up with: "sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set"
What do I do? I'm new to Ubuntu and Linux in general.
