On Sunday September 28th 2014 the GPG key for our Apt repo data expired. This affects users of Debian, Ubuntu, and other Apt-using systems.
This is the key for the package version info and metadata provided by the repo to your favorite package manager, not the key with which all our packages themselves are signed. Because of this Apt users will see the following error when attempting to upgrade (via apt-get) with the old key.
“An error occurred during the signature verification. The repository is not updated and the previous index files will be used.”
To address this, we ask that users install the latest key on their Debian, Ubuntu, or other Apt-based systems with the following command:
curl https://apt.appneta.com/appneta-apt-key.pub | sudo apt-key add -
This will download the latest key from our server and add it to your APT key. To confirm the latest key is added correctly and that nothing else has changed compare the output of `apt-key list` from prior to adding the new key to afterward.
