[karmic] sudoers corrupted - all root xs lost :((
Ok, i made a mistake by entering a faulty line into /etc/sudoers
And before that another one by forgetting my root passwd
However, i did not expect sudo to stop working completely when it has 1 bad line in /etc/sudoers
I also did not expect that every tutorial on how to reset your root passwd just doesn't work for me.
Rebooting into recovery mode gets me a root prompt that is unable to use passwd.
Something about failure to update the token, file-system read-only.
But mount reports that it's in rw. strange.
Holding shift while selecting recovery mode in grub (which is a STUPID way to get to an extra menu btw) gets me a menu that i'm unable to navigate with the cursor keys. After a few seconds, it nags about not being able to mount file-systems, then continues booting to a login-prompt, which is of course useless to me at this moment.
FFS, go fix this huge bug, starting at /etc/sudoers.

help with this would be much appreciated.
Re: [karmic] sudoers corrupted - all root xs lost :((
Ok, i was able to solve the problem like so:
- boot off ubuntu karmic live CD
- goto Applications | Accessoires | Terminal
- enter these commands:
sudo fdisk -l
(then note which /dev/xxxx entry is your now-faulty root filesystem)
sudo mkdir /media/x
sudo mount /dev/xxxx /media/x
sudo apt-get install vim
sudo vim /media/x/sudoers
Still, the original report stands. It could've been a lot easier to solve if sudo isn't quite so paranoid.
