Hi,
You can use the CLI (or terminal) to login to root.
use the command su like this:
go to K | Terminal | Gnome-Terminal (or any other)
you will be presented with
user@localhost user/#
type in:
user@localhost user/# su
password
Enter the password for the root acount.
Now go to the location of your RPM by using the cd command
user@localhost user/# cd /home/username/dir-that-was-the-rpm
user@localhost user/# rpm ipq *.rpm
This will produce a list showing if the package will install or if any other dependances need to be pre-installed.
If this dies then it is the rpm that is curpt.
