which gsettings
~/.anaconda3/bin/gsettings
$ ll ~/.anaconda3/bin/gsettings
-rwxrwxr-x 1 user user 50633 kesä 5 18:13 ~/.anaconda3/bin/gsettings*
And there was the problem! I just had not realized it so far—anaconda had hijacked gsettings!
Solution: I went to ~/.anaconda3/bin/gsettings and renamed it as ~/.anaconda3/bin/gsettings_old.
It works now! Thank you so much!! 
hopefully, this will also help someone else using anaconda (python package)
