For nearly a week now, Google Play has been haunted by an annoying error that seemingly strikes at random. Upon downloading and/or updating certain apps, many users (myself included) have ran into a “Package file is invalid” error. It doesn’t matter what app you are downloading or updating. Sometimes the error happens, sometimes it doesn’t.
While these kind of problems often are user errors, that’s not the case here. The problem seems to have to do with corrupted Play Store data, and according to Google, they are aware of the issue and looking for a permanent fix.
Google Support has now put up a page for the Package File Invalid error (#10230007), which it will keep updated as it learns more and comes up with a solution.
In the meantime? Our best advice is to wait a bit after receiving the error and try again. We’ve also heard of some (limited) success for those that have switched connection type after encountering the error, such as going from Wi-Fi to mobile data. That said, there are no real fixes at this point.
Rest assured that Android Authority will be sure to post more information once Google fixes the issue for good.
