The error is telling you that your sources can not be read because you have a bad entry in line three of the file at /etc/apt/sources.list.d/signal-xenial.list
. You need to remove or comment this line, or delete this .list
file.
You didn't tell us what version of Ubuntu you are using but please be aware that community support has ended for Ubuntu 16.04 (xenial).
