Update the GPG key for Treasure Agent

Hi folks,

This article is for Treasure Agent users.

We used SHA1 based GPG key for td-agent package signing, but SHA1 has beed deprecated. For example, apt will remove SHA1 support: Teams/Apt/Sha1Removal - Debian Wiki

So we have updated Treasure Agent's GPG key for deb/rpm to drop SHA1 based signing. It means you need to update imported old GPG key before td-agent update.

If new deployment or if you disable gpg check, no need update action.

Here is an update steps for deb/rpm.

deb

Remove old GPG key

% apt-key del A12E206F

Import new GPG key

% curl -O https://packages.treasuredata.com/GPG-KEY-td-agent
% apt-key add GPG-KEY-td-agent

You can check imported is succeeded or not.

% apt-key list

Error content

Here is error example with old GPG key

W: GPG error: http://packages.treasuredata.com/2/ubuntu/xenial xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 901F9177AB97ACBE

rpm

Remove old GPG key

If you found this key in rpm, remove it by following command:

% rpm -e --allmatches "gpg-pubkey-a12e206f-*"

Imoprt new GPG key

Import by rpm import

% rpm --import https://packages.treasuredata.com/GPG-KEY-td-agent

You can check imported is succeeded or not.

% rpm -qi "gpg-pubkey-ab97acbe-*"
