I have a lineageOS with microG phone with a unusal problem. I haven't seen it, at least.
I tried to install my old banking app again from Aurora, in the hope it could work again (it used to, but stop a few months ago after an update). Well,, Aurora downloaded the app, but its stuck on the install part, with the "circulating round thinghy" on it. I tried to kill aurora, reboot the phone, nothing. If I open aurora and go to this app, it keeps on the "installing" status. The funny thing is that I can install or remove other apps just fine, even thru aurora.
Any Ideas?

Download instead, install through this so you can try different options. It's worth a try.

That's not an unusual problem at all. Happens basically every time. Just ignore it and eventually it will get installed.

I have seen this happen before on certain phones, it ended up working after just putting down the phone and waiting a bit.

Cant hurt to check if one of these fix it tho

• Aurora might be trying to show you an android install prompt, but those cant be shown if something is overlaying your screen (eg. pop-up video)
• Clearing Aurora app cache in android settings.
• You could try with Auroras Nightly app to see if it works better.

I've had that problem for a long time. Never found any solution.
