Solved, i upgraded domoticz to beta ..

[waaren]

dpkg --get-selections | grep libpython

I am on different hardware (Intel NUC) but also on bullseye.

Code: Select all

dpkg --get-selections | grep libpython | grep -Ev "2.7|3.7|3.8"

libpython3-dev:amd64                            install
libpython3-stdlib:amd64                         install
libpython3.9:amd64                              install
libpython3.9-dev:amd64                          install
libpython3.9-minimal:amd64                      install
libpython3.9-stdlib:amd64                       install

Seems the difference is libpython3-dev:amd64
