Can't update installer

[I'mAMac]

When I open up installer it asks me to update and I say yes but then it always says error package failed. Does anyone know how to fix this? Thanks

you've probably run out of app space on your ipod. i solved this by re-jailbreaking my ipod (with that z___ app), then installing bosstool from the utilities thing. this tool moves stuff so you have room for more apps
