I have set up Airflow on an AWS EC2 server with Ubuntu 18.04, Python 3.6.9. The DB backend is a 5.7.26 MySQL, I am using a LocalExecutor. The setup is nothing more than:
apt-get install python3 python3-pip python3-venv libmysqlclient-dev
I install Airflow with pip3 install apache-airflow[mysql]==1.10.9, init DB connection, start the webserver and it works both normally and with -D. The scheduler, however, works only when run in the foreground. Trying to run it as a daemon fails with the following trace:

I am trying to set up a server for semi-production purposes, so this is actually a blocker for me. I would be grateful for any advice.
EDIT
I tried using mysql-connector-python==8.0.18 and the scheduler did run as a daemon, but an attempt to open a dag failed with the following trace:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte
The above exception was the direct cause of the following exception:

What finally did work was using mysqlclient by specifying the SQLAlchemy connection string to begin with mysql+mysqldb. I am not giving this as an answer, because the initial problem persists.
I'm on Manjaro Linux KDE and every time I try to install a module with pip it gives me this error:

Also, when I try to run a program where I imported selenium or any other installed module from pip it gives me the same error.
This is my pip version: pip 20.0.2 from /usr/lib/python3.8/site-packages/pip (python 3.8)
Thank you all in advance!
Software stack version:

When running Zipline from terminal just to try it out:
$ zipline run -f buyapple.py --start 2000-1-1 --end 2014-1-1 -o buyapple_out.pickle
The following error appears:

I have also tried putting the SPY_benchmark_data.csv directly inside the .zipline/data/ folder, and still the error is produced.
I have also tried a clean install of conda and python env 3.4 -- same issue.
I installed pylint via pip (version 9.0.1) on a Windows 7 machine with Python 3.5.0. The installation succeeded, but invoking Pylint returns an error "RuntimeError: Inconsistent hierarchy". Any ideas on how to troubleshoot this?
