When setting up the CUWB installation system, we followed the best practices at the time. Unfortunately since that time the best practices have changed and in the meantime the APT package signing and verification keys we were utilizing expired.
We have since updated the signing keys to the latest standards. Unfortunately this means that anyone who installed prior to July 25, 2019 will need to update the verification keys. Fortunately there is a relatively simple process to updating.
To update the verification key, just run the following from any terminal.
Terminal - /home/cuwb
- sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 13FB78B5
- wget -qO - https://cuwb.io/ciholas.pgp | sudo apt-key add -
