Custom .deb does not install all files

Solution 1:

I figured out what the problem was.

I tested my .deb file via cycles of the following two commands:

• sudo dpkg -i fman.deb
• sudo dpkg -r fman (equivalently, sudo apt-get remove fman)

I found out that ... -r excludes config files. To also delete config files, one must use sudo dpkg -P fman.

During my testing, I must have manually deleted /etc/apt/sources.list.d/fman.list at some point. But dpkg (/apt) still remembered that it had installed that file, so it didn't re-install it the next time I did dpkg -i (equivalently, apt-get install).

The solution was therefore to call sudo dpkg -P fman. The next time I then did dpkg -i fman.deb the fman.list file was created as expected.
