I also just got "Unfortunately, the package access manager has stopped" trying to do the clear cache.
Note, Manager not helper. Also getting helper stopped.
HAHA you guys are so silly. its like you don't read the whole thread. there are TONS of people having this issue. Ive done the Cache refresh fix and ive done the factory reset. the error pops up randomly. its so great to pay 101$ a month and have a phone that doesn't work. The problem is not with third party software as you guys keep saying in the thread the problem is with lollipop upgrade that you guys put out. Whats the point of paying for a smart phone when you can only use it to text and make phone calls might as well have a flip phone.
I also am getting this exact same error and problem - even with my SD card removed, all apps (whether from the Google Play Store, or from the Amazon App Store) get stuck on "installing". Has anyone had any luck with a fix?
I want to make sure that I help you as much as I can magus824! What is the make/model of your device? What troubleshooting have you done so far? I do know sometimes applications are not able to be moved to the SD card. This is a normal function of the device. I do know updates are suppose to improve your phone and sometimes they can change things as well. You should still be able to download apps to your phone. Are you able to download any other apps?

As an additional follow up. It appears that if you have enough access to your device to run pm from the shell, you can tell pm (package manager) to install to internal rather than automatic. This will allow applications to install from third party sources without having to remove the SD card. I believe this also requires root though unfortunately.
I'm personally using Link2SD with App2SD setting my installations to internal and then Link2SD remapping my installations to an EXT4 partition on my SD card to avoid remapping issues, but again, that's only an option on a rooted device. Otherwise, it is up to Verizon and Samsung to fix the permission issue as the permission issue involved is a hard coded kernel permission group issue that is impossible to fix without a kernel recompile (and thus also inaccessible to anyone not on a developer edition device until Verizon releases an official signed build.)
I'm also running into this issue. I can't download any apps from the play store. I can download from the amazon store if I unmount the SD card. This is the error is recieved 'Package Access Helper has stopped'
I would like to add/clarify that since the Lollipop upgrade I have been unable to move [large] applications from main storage to my SD card. I receive the same error everyone else has mentioned, the package access helper has stopped.
