-To correct the repository origin, execute the following command as a privileged user:
pkg set-publisher -O
To add a new publisher using this publisher's repository origin, execute the following command as a privileged user:
pkg set-publisher -O http://pkg.opensolaris.org/dev/

Update succeeded to 130.
