You got it backwards!

You're the one having a problem and wanting it fixed. So it's your obligation to pay attention to what people ask of you and answer all their questions as precisely as possible - because they pose them for good reasons.
So far you're not doing this, which is why this thread is going nowhere.

For example, you've been asked which repos you use (because it is suspected, that you accidentaly use N9 repos). A precise answer would be to quote the strings from your package manager of choice - to the letter(!).
I suggest you re-read the whole thread from the point of your first post, scan for any questions directed at you and think very thoroughly about how to answer every single one of them as precisely as possible.
