install error - "package is of bad quality"

I just installed 5.1.4.2 /DEB 64 English help file.

I tried to use Ubuntu Software Center to install the file, instead of through the "terminal" command.

I received an error message stating "the package is of bad quality".

I was able to install it using the "sudo dpkg -i *.deb" terminal command. So I am wondering if there is something in the 5.1.4.2 DEB 64 English help .deb help file that is not compatible with Ubuntu/64 16.04 LTS.

Any ideas what is wrong?

Since I installed 5.1.2.x using the terminal commands on Ubuntu 15.10, then I upgraded to 16.04LTS. This was the first time since I installed 5.0.x that I tried using the Ubuntu Software Center to install the help file.
