Duplicity is giving a TypeError when uploading to Google Cloud Storage

I have a backup script that has been working fine. I recently updated my OS (to Ubuntu 19.10) and tried to install all of the dependencies but I'm getting an error.
My script is something like:
export PASSPHRASE="passphrase"
PATH=$PATH:/home/jeremy/.boto
export HOME='/home/jeremy/'
DATE=`date +%Y-%m-%d:%H:%M:%S`
echo "Running backup at $DATE" >> /home/jeremy/.backup/log
duplicity --full-if-older-than 1M \
--archive-dir /home/jeremy/.cache/duplicity/ \
/home/jeremy \
gs://x1_carbon_backup >> /home/jeremy/.backup/log
I created the .boto file with gsutil and I can use gsutil successfully, so authentication appears to be working.
The traceback looks like an encoding/decoding problem but I can't tell if it's a problem with how I'm doing things or a bug in boto or duplicity

PyMongo - Server timeout on localhost

I'm trying to learn how to work with MongoDB in Python but everytime I run my code it takes so long that I have to kill it and I get these tracebacks.

This is my code:
import pymongo
client = pymongo.MongoClient("localhost", 27017)
database = client["database"]
high_scores = database["highscore"]
mydict = {"highscore" : 5}
x = high_scores.insert_one(mydict)
print(x.inserted_id)
My belief is that it cannot connect to the localhost

Apparently mongodb was not started on my PC. All I had to do was to run
brew services start mongodb
and it worked perfectly.

Error connecting to PyPy3 multiprocessing remote manager

Turns out to be a bug in PyPy3.
