This is likely because you switched python versions in a weird way. Do you have /usr/lib/python3/dist-packages/apt_pkg.so ? This can be missing if you removed a version of python.

The answer that worked for me was this from askubuntu forums:

ln -s /usr/lib/python3/dist-packages/apt_pkg.cpython-36m-x86_64-linux-gnu.so /usr/lib/python3/dist-packages/apt_pkg.so
