I am new to GOS and Android as of yesterday.
I have f-droid installed on my main user (owner) and decided to tinker with setting up a second user. For the second user I have allowed permissions for installing all apps.
The second user account setup went smoothly. I installed the three google apps required for sandboxed play store, then proceeded to f-droid's website to download it.
F-droid downloads but when i click to install, it says "App not installed as package appears to be invalid."
I created a third profile, did the exact same thing as with profile two, and am also not able to install f-droid. Then, I created a fourth and tried to install f-droid before GPS, also got the same message.
Any ideas?
