how come everytime i try to install a source on cydia, like imobilecinema, it saids , bad url or cached failure? can somebody please help me

here are a few possible explanations,
1) The repo is down, check the forums for more information.
2) You typed it wrong, many people forget to put the / at the end of a repo url.
3) You aren't connect to a network , pretty self explanatory.

does any of these help?
