Cannot install/uninstall apps

I have a problem with managing apps in F-Droid.
There are a lot of them which I can’t install because F-Droid App tells me that I have them already - which isn’t the truth.

There’s information that there’s no version with compatible signature, and that I need to uninstall them first to get them from F-Droid. (I get that - since they are signed with different sig - that’s not the problem)
But I cant do it - those apps are greyed out on the F-Droid App list and there’s no uninstall button. And since I have never installed them - they are not listed in system apps list in the first place.
This occurs whether Google Play Store / Services are enabled or not.
The phone is freshly rooted Galaxy Note 5 N9200 HK.

Thanks in advance for every answer.

Which apps are concerned?
Could it be they are pre-installed by the system but hidden from the apps list?

I think that’s highly unlikely to have all of them preinstalled in vanilla device.
Things like xposed, yalp store, tinc, xserver, wlanscanner, ethereum wallet, wake-on-lan, vespucci, unifiedNlp (no GAPPS), and many others.

Those apps are not listed in system list, and I can’t locate any trace of them in file system.

That’s strange. :confused:
Did you try clearing F-Droid’s app data in the system settings?

Thanks for the tip paulakreuzer!

I’ve found the solution:

  1. Clear app data
  2. Uninstall F-Droid
  3. Clear app data again
  4. Install F-Droid

Also the problematic apps didn’t have icons displayed in F-Droid App.
Unfortunately clearing cache and app data did not worked - reinstall is required.
Freshly installed FD app find only apps that I have installed manually.

Case close I pursume.
Thanks again.
