I am tying to install Dayon! (an open-source and cross-platform (JAVA) solution that allows watching and controlling a remote computer) from https://github.com/retgal/dayon/releases.
I have downloaded a .deb file from here, verified the md5sum and opened the Tilix terminal. I get the next message:
snailmail@snailmail-pc:~/Downloads$ sudo dpkg -i dayon*.deb
