The main issue is the pip/pip3 command cannot be found when the package is being installed by apt-get.
When using the dpkg install, the searching path is PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
When using the apt-get install, the searching path is PATH=/usr/sbin:/usr/bin:/sbin:/bin
But the pip/pip3 default path is at /usr/local/bin, so dpkg works, but apt-get not work.

How I did it

Export the path /usr/local/bin for pip/pip3.
Make the deb packages can be installed by apt-get.
