As an alternative, I get the following from using "sudo apt-get update" http://dpaste.com/2NZ5H5T

  • I can't update from app center or the $ prompt, I get this error: E: Type '<!DOCTYPE' is not known on line 2 in source list /etc/apt/sources.list.d/signal-xenial.list E: The list of sources could not be read.
