The Ubuntu 11.10 PC resets resolv.conf on each boot, only with a comment remaining.

How do I fix this by setting the persistent storage?

It was tinkered by somebody else and I (and him!) cant trace his actions. The graphical connection manager also refuses to work thanks to the tinkering.

Content of interfaces file:

root@technovia-3:~/dev/spectrum/spectrum# cat /etc/network/interfaces 
auto lo
iface lo inet loopback

When theres a manual entry in the /etc/network/interfaces, Your graphical network interface wont work.

Either you remove the entries in interfaces file in relate to the interface(eth0,eth1) you are working on. Then restart networking using sudo /etc/init.d/networking restart, after which you can use the graphical interface

Or edit interfaces file to include nameservers, like dns-nameservers <ip> and restart networking.

Posted the file – aitchnyu Jun 13 '12 at 9:40
@aitchnyu that means loopback interface, thats wont be a issue.Then you should be able to manage the interface graphically. If you dont get a icon, then try sudo /etc/init.d/network-manager restart Or else add entry in interfaces – Vishnu Kumar Jun 14 '12 at 8:08
