Well, now Ubuntu won’t start. Saying something like sh cannot be found. I’m going to do some research in Ubuntu Forums.
Eeeeeeeeeeeeeeeeeeek!
Terribly sorry. But you should be able to “rescue” the install simply by booting from the install/Live-CD thingy.
It should detect the ubuntu install and automatically mount it.
Then you should be able to issue the correct symlink command, to link /bin/sh -> /bin/bash.
You probably want to check its right by doing a
ls -al /bin/shthe path will be something like /media/hda3/bin/ though, not /bin.
