I am going to assume that you are referring to the fact that there is no .deb GUI application to handle installs and therefore you cannot just click the .deb file.

I was able to install Trillian without issues by doing the following:

  1. Downloading the .deb file from their website: https://www.trillian.im/get/linux/2.0/linux.html
  2. Using Terminal: sudo apt install /path/to/file.deb
