How do I fix package invalid error on Google Play for android?

[Shivani]

The newest version of Google Play (build 4.3.10) is apparently causing a number of problems for users who are trying to update apps. Both our comments and a variety of forum threads are filled with readers who are receiving a “Package file is invalid” error during updates. The error isn’t showing for all apps, nor have we been able to figure out a pattern. At times, the error presents itself with Google apps, while at other times they update fine. We’re also seeing the error for non-Google apps, but again, it’s tough to figure out why and when it will happen.
