Error: Package could not be unpacked

[Jasper44]

Installer is giving me that when I try to update applications or install anything new. It says I have 103.8 MB of memory available so that can't be the problem but I can't figure out what the issue is.

I had that problem about a week ago, where no applications would install correctly from installer.app. The problem went away for me, though in about 2 or 3 hours...

It's been happening for a couple days. I have a bunch of stuff to update but none of it will.

needs to be on write to mode, meaning needs to be jailbreaked again.
