Sudo: Unable to resolve host: hostname

[leech38128]

I don't know if this has been talked about yet, since I could not find it anywhere in the forums...
I cannot seem to use 'sudo <command>' without getting 'sudo:unable to resolve host: hostname.

leech@stephanie:~/Templates$ sudo ./configure
sudo: unable to resolve host stephanie

I have even tried to use this command as the root user to no avail. I am running Hardy x32 NOT from an upgrade. I don't have anything non-standard install besides AWN and Screenlets, which I installed through 'Synaptic'.
Any help on this would be graciously accepted.

I ran into this problem yesterday, after playing around with Samba. Samba had modified the entry in /etc/hosts for my machine.

Go to System -> Administration -> Network -> Hosts

Check the entry for 127.0.1.1 and see if it matches the hostname of stephanie. If not, change it back to stephanie.

I had the same problem. The Monicker's solution has solved it. Thanks.

...Yeah, I was wondering the same thing!! Especially, since YOUR post has the "thanks" icon (lower right, a little yellow star + blue badge, next to "quote"/"reply") -- and the other posts do not..!?

Then, I found this in one of the forum how-to's: "All about the Thanks feature":

"A few notes:
* The Thanks feature doesn't show up on posts that were in existance before it was implemented.
* The option to remove the Thanks shows up after you Thank someone.
* Not all forums have this feature.
* The ability to thank a post seems to disappear after 60 days."

cheers,

I'm running Karmic on an ASUS EeePC and I had a similar problem and solved it by doing the following:

I originally had a hostname of - ASUS EeePC

I think the space between the word was the problem. I looked at all the files related to hostname:

cat /etc/hosts

cat /etc/hostname

hostname --long

And they all had the same hostname 'ASUS EeePC' . . . so I decided to make a change and see what happened.

I edited the file /etc/hosts and /etc/hostname and changed each to just - 'EeePC' (w/o the quotes) without any spaces.

I rebooted and everything was working fine . . . other parts of the files got updated/modified to add the 'localhost' and 'local-domain' elements discussed in this thread and in others. And no more sudo error messages.
