The auto-upgrading sensor package is named cwp. To install it, first uninstall the existing package (previous packages are named canary-forwarder or canary_forwarder) then install the auto-upgrading package.
Note: These steps are relevant if there is an existing deployment of the sensor as either canary-forwarder or canary_forwarder. New deployments using the cwp package do not have additional steps.
Steps
Debian
sudo apt remove canary-forwarder
sudo apt autoremove
sudo apt-get update
sudo apt-get install cwp
RHEL/Centos 6, 7, 8
sudo yum remove -y canary_forwarder
sudo yum install -y cwp
