[cobalt-developers] root access problem

["Edgar F. Flores Muñoz" <ed@xxxxxxxx>]

Recently when trying to change me to root this error does appear, does
somebody know to what it is or as I can correct it?

[admin admin]$ su -
Password:
su: warning: cannot change directory to /root: Permission denied
su: cannot set groups: Operation not permitted

Ahead of time I thank you the help.
