Can confirm with python3-pip-whl on mintupdate 6.0.1

The problem is that the update applies to more than one package (xxd and vim or python-pip and python3-pip-whl) but checkAPT.py#L256 gets the description for the first package even if it's not installed:

python-pip                  <-- FOUND
python-pip
python-pip
python-pip=22.0.2+dfsg-1ubuntu0.3
python3-pip-whl             <-- Package installed
python3-pip-whl

In the vim case, xxd is one of the packages in the update. It is the last listed. The packages are
vim-common
vim-tiny
xxd
