By the way, the last couple of days I keep getting
sudo: unable to solve host ubuntu
every time I use sudo, but it still works. Should I worry about it?
Thank you very much if someone can help me with that.
Have a look at your /etc/hosts and /etc/hostname files and make sure they both have the same entry for your machine name. That should be the same as the name that shows in your terminal prompt, ie, username@hostname, and needs to be the same in both of those files. If one of them is incorrect, edit it with
Code:
gksudo gedit /etc/hostname
.
