problem with "sudo su"

[Gerardo Castro]

Binary package hint: gnome-terminal

Sometimes (I couldn't yet determine in which cases), when I type 'sudo su' in terminal, I am not asked for a password, the console outputs this:

gejo@lamaquina:~$ sudo su
(sudo: unable to resolve host lamaquina)
gejo@lamaquina:~$ root@lamaquina:/home/gejo#

If I press enter it returns me to the user prompt

gejo@lamaquina:~$ sudo su
sudo: unable to resolve host lamaquina
gejo@lamaquina:~$ root@lamaquina:/home/gejo# [enter]
gejo@lamaquina:~

If I press any other key, gnome-terminal closes.

If I open two or three terminals, then it works in the second or the third(couldn't determine when nor why),
It prompts me for a password and then I can work as a superuser till I exit.

Thank you, gejocastro.

though this is probably more suited as a question than a bug report I will leave it to you or a triager to make that conversion.

(sudo: unable to resolve host lamaquina) indicates your host name in /etc/hosts doesnt match your hostname in /etc/hostname.

To resolve that issue change /etc/hosts and remove any suffixes to the hostname. starting in early alpha of ubuntu 8.04 this has been an issue. It is probably best to do this from a root login (recovery mode)

Once you have done this the sudo problems should disappear.

Not seeing this in konsole-kde4

Something I've read recently prompts me to ask, have you change the network name of your computer since you set it up?
