Troubleshooting Automatic-Update Problems on Enterprise Agents

ThousandEyes software is architected to run a version check upon check-in with the ThousandEyes collector. This process will validate the currently installed version of the agent against the expected version in our system. If running a version lower than the expected version, the Agent will download the required packages, and update them.

This process is run during the update:

Ubuntu

Red Hat Enterprise Linux/CentOS

apt-get update

yum update

apt-get install te-agent

yum install te-agent

apt-get install te-browserbot*

yum install te-browserbot*

* The te-browserbot package is only required for instances running a browserbot installation. This does require additional resources on a Enterprise Agent (minimum 2GB RAM is recommended)

GPG error: http://apt.thousandeyes.com lucid Release: the following signatures couldn't be verified because the public key is not available: NO_PUBKEY C99A1F5BE718900

When this occurs, a manual download and registration of the ThousandEyes public key is required. This can be done in either one or two steps: the one-step approach is shown below:

wget -q http://apt.thousandeyes.com/thousandeyes-apt-key.pub -O- | sudo apt-key add -

This will download and register the ThousandEyes public key, which will allow you to re-run the steps above as required in order to update the agent codebase.
