errror while installing/replacing python 3.10

Hi!

I am make-replacing packages on my SS20 running 9.2

pkg_rolling-replace stopped in python...

<... many more errore ...>

Stop.

*** Error code 1

I wonder what is it trying to do, remove an existing python installation?

/usr/pkg/lib/python3.10/

exists, but there are few files inside.

$ pkg_info | grep python
python38-3.8.10nb1  Interpreted, interactive, object-oriented
programming language


tells me only 3.8 is registered as installed....
I did run pkg_admin rebuild-tree without success.
