I have done a lot of searching but still am stuck with this problem. Since updating to the latest Cyanogen Rom, I am getting a lot of "package file invalid" errors when trying to install or upgrade apps. Some will go through ok, others display the message I have just mentioned. Really, I am stuck! I do not have a clue what to do and can't find anything though searching that will help. Just remembered, a lot of apps also crash whilst running, not sure if that is a related issue.
I have attached a log file though really, I have no idea what any of it means!
Any and all help appreciated.
