Can't install f-droid or other APK (except from google) on lineage 19

Hi, I can’t install .apk from repo outside of google store. I’ve tried f-droid, aurora, without success.
My phone is a nokia 7+ with lineage 19.
Can I post further details and captures here for help ?
Thanks

PS This is my first smart phone with android, bear with me…

What error do you get?

Where did you install gapps (Google Apps) from?

Thanks for your response.
Sometimes I got no notification at all, just nothing happens, sometimes I got “package installer kit automatically stopped”

Google was installed when I bought the phone.

Some captures if this may help:




You need to find a proper OS, not an unofficial pre-release build of LineageOS.

OK thanks I’ll look to find something compatible and with a smooth install learning curve.

Did you buy the phone with that ROM preinstalled? If so I would definitely reflash anyways. Would be a bit dodgy if they weren’t even selling a proper lineage version
