Zigbee Gateway and Thread Border Router `apt-get install` key issue

[ Edited ]

When using the `sudo apt-get install` method for the Zigbee Gateway and Thread Border Router reference designs the following error is likely to come up:


W: An error occurred during the signature verification. The repository
is not updated and the previous index files will be used. GPG error: jessie InRelease: The following signatures
couldn't be verified because the public key is not available: NO_PUBKEY
7378FB7890CE4F77 W: Failed to fetch W: Some index files failed to download. They have been ignored, or old
ones used instead.

This is because the aptly server used was updated, and keys were changed in the process. To get around this error just run the following command, and try the apt-get update again:


sudo apt-key adv --keyserver --receive-keys 90CE4F77
