i’m getting this error after trying to install any .rmp package. I’ve tried
sudo zypper rr 2
sudo zypper rr1
sudo zypper clean -a
sudo zypper ref
but after that i get a Could not find the rpm-Package in Pool error

Please, post the output of
zypper lr -u
Also tell us what command you use to install the rpm after the four invocations of “sudo zypper” you say.
