Debian 10 Instance Pip3 Error for certain packages
Hello,
I recently created a new Debian 10 instance, and when I try to use it to install certain packages, I am getting this error. It also happens if I try to update the pip3: sudo -H pip3 install --upgrade pip
Any ideas for why? Thank you.

I just tried this out on a fresh Debian 10 install as well and was unable to recreate the issue. Here were my versions:
python3 --version
Python 3.7.3
pip3 --version
pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)
For the record, I used sudo apt install python3-pip to install pip. When I ran the installation command for beautifulsoup4, this was the output:
root@localhost:~# pip3 install beautifulsoup4

My suggestion is to make sure all your packages are up to date with sudo apt update -y && sudo apt upgrade -y then try the install again. If that doesn't work, you may want to upgrade to the latest version of Python if you haven't already.
