You did not say how you upgraded or installed software

By default "apt-get" behaves different, than "apt" does, you temporarily
could change the default by adding "-o APT::Keep-Downloaded-Packages=1"
or permanently change the behaviour by editing the apt settings. I
don't have at hand how to permanently edit the settings, Google is your
friend.

IOW running

sudo apt full-upgrade -o APT::Keep-Downloaded-Packages=1
sudo apt install -o APT::Keep-Downloaded-Packages=1 <package>

does the same as

sudo apt-get dist-upgrade
sudo apt-get install <package>

Regards,
Ralf
