I follow instructions on Gumstix Wiki to install Ubuntu 10.04 onto Gumstix Overo. Installation was success and system booted correctly. At the user prompt, I cannot login as root. So I follow instructions from the wiki:
The rootstock utility doesn't make passwords properly. For
now, it is easiest to remove the root password, boot your system to
create new users and choose a new root password. To do this, open the /etc/shadow file on the second partition and delete the '*' for the root entry. E.g.
$ sudo gedit /path/to/second/partition/etc/shadow
Note: remember to put the ‘*’ back after you have created a user so someone can’t login as root and screw up your system
but I have no shadow file in this path! I created an empty shadow file, and re-booted Overo. Still same problem, cannot login as root or as any other user. What can I do? Do I also need to edit /etc/passwd ?
