As a Ubuntu or Debian user you may occasionally get an error like the following:
E: Repository ‘http://dl.google.com/linux/chrome-remote-desktop/deb stable Release’ changed its ‘Origin’ value from ‘Google, Inc.’ to ‘Google LLC’ N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
Unfortunately this message doesn't actually tell you how to accept the new origin. It is however as simple as running:
sudo apt update
You will then be prompted with a [y/N] question which allows you to accept the new origin.
