ValueError: can't have unbuffered text I/O at simon start

[juanfariaso]

Hi,
I am having trouble starting simon on two systems, one with a fresh install of python3 (on a docker image) but on my local computer as well.

I installed simon with :
python3 -m pip install astrosimon

which currently install astrosimon-0.8.5

the simon command works but the daemon seems to fail:

Can you reproduce this error on a fresh install?

I tried installing directly from git but there I got a different error, I could open another issue for that.

Any ideas?
