unable to resolve hosts

Asked by kjerryn

hello,
i just upgraded to hardy and in terminal the sudo results in unable to resolve hosts.
i followed a contributor to the forum to use a passwordless root as system boots to see the contents of /etc/hosts
which is 127.0.0.1 localhost
             127.0.1.1 kwam-desktop.kwam
i tried changing the second line to kwam
reply was [error writing /etc/hosts: read-only system file]
what do i do?

hi
i just tried the passwordless root as system boots to see the contents of /etc/hosts
which is 127.0.0.1 localhost
             127.0.1.1 kwam-desktop.kwam
and tried to add to the first line.
the result is the same [error writing /etc/hosts: read-only system file]
how does one get out of that place anyway? typing reboot, shutdown, exit does not really do anything. i've had to cut power to shut down

You may ever
- follow the steps in the thread above without forgetting the "rw" option on the command line
- Or when you press ESC to access the grub menu, simply select recovery mode.
- If all that fails and you still have a read-only filesystem the execute "mount -no remount,rw /" (if /etc is on the same partition as /"

hi
the problem was solved with

gksudo gedit /etc/hosts

and making the hostname the same as that in

cat /etc/hostname
