Issue body
I utilize charmcraft inside a docker container... which rebuilds every 30 days.. or so. Anyway, it was working fine until a day ago
```
FROM ubuntu:20.04
ARG DEBIAN_FRONTEND=noninteractive
RUN apt update
RUN apt upgrade -y
RUN apt install python3 python3-pip libffi-dev libapt-pkg-dev libssl-dev python3-venv -y
RUN pip3 install https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/python-apt/2.2.1/python-apt_2.2.1.tar.xz
RUN pip3 install charmcraft
RUN charmcraft version
RUN python3 --version
```
The main error I see is the following
```
