** Description changed: I stumbled upon this error after upgrading to 8.04 yesterday and while trying to use sudo. It have me the following error, sudo: unable to resolve hostname <HOSTNAME> I checked the /etc/hosts file and found the following entry, 127.0.0.1 <HOSTNAME>.<DOMAINNAME> <HOSTNAME>.<DOMAINNAME> I removed the <DOMAINNAME> from the second occurrence and things started working fine. - However when I switch the network settings through System -> - Administration -> Network. Again the same setting reappeared. I though - that the error might be with the hosts tab in the switched setting and + However when I switched the network settings through System -> + Administration -> Network. Again the same setting reappeared. I thought + that the error might be with the hosts tab in the switched setting. So I removed the domain name from the hosts tab and clicked apply. But the - /etc/hosts wasn't changed. + change didn't get reflected in /etc/hosts. Here is a detailed procedure to reproduce this issue, - Go to System -> Admin -> Network - Click unlock and enter your password - Select a setting from the Location drop down - Go to hosts tab - Select the "127.0.0.1 <YOURHOSTNAME>.<DOMAINNAME> entry and click "Properties" - Append your host name without domain name to the value part and click "Ok" and then "Apply" - Do cat /etc/hosts and notice that the /etc/hosts has wrong entry as, 127.0.0.1 <HOSTNAME>.<DOMAINNAME> <HOSTNAME>.<DOMAINNAME> instead of 127.0.0.1 <HOSTNAME>.<DOMAINNAME> <HOSTNAME> The only way I am able to remove it is using the root account (I had once set the password using "sudo passwd" when /etc/hosts was correct) Here is my OS version info, > uname -a Linux lap432 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux
