I typed the command. It's wine 1.4 Okey I found something about creating new user. And I created one. I found how to on this link and named it normaluser http://www.howtogeek.com/50082/create-a-new-user-on-ubuntu-server-9-10/ Now to switch to that user I typed. Code: sudo -i -u normaluser Now following how to in the second post I tried to change directory to that particular folder named Vagex on desktop. But the permission is the issue now as you can see in the code bellow. Code: normaluser@cloud-4f800bb5109cd:~$ cd '/root/.wine/dosdevices/c:/users/root/Desktop/Vagex' -bash: cd: /root/.wine/dosdevices/c:/users/root/Desktop/Vagex: Permission denied normaluser@cloud-4f800bb5109cd:~$ sudo cd '/root/.wine/dosdevices/c:/users/root/Desktop/Vagex' [sudo] password for normaluser: normaluser is not in the sudoers file. This incident will be reported. normaluser@cloud-4f800bb5109cd:~$ So now what?
