Need a little more info than that. What exactly are you trying to install?

[marxus79]

Mostly themes but now cant remember which ones

It may be that they havent been updated to support whatever firmware you are on.

Has nothing to do with firmware. It means that the size of the download doesnt match what size its expecting. Its the repo u are getting them from. Let cydia update sources/packages n try again. Worst case reboot ur phone and let it update.
