Software installation problems on core 3
 

I've had all sorts of problems installing apps in core 3. Do not send me links to pages instructing as to how to install apps. I know how to install rpms & how to install through yum and such, it's just that they don't seem to install successfully. Is there an app that someone has successfully installed on core 3 that I could give a try installing? I think part of my problem may be compatibility issues with core 3 (just a hunch, I'm a noob to linux). So I thought I'd give this a try. Thanks.
