Update the Signing Key for Percona Debian and Ubuntu Packages
In this blog post, we’ll explain how to update thesigning key for Percona Debian and Ubuntu packages.

Some of the users might have already noticed following warning on Ubuntu 16.04 (Xenial Xerus):

W: http://repo.percona.com/apt/dists/xenial/InRelease: Signature by key 430BDF5C56E7C94E848EE60C1C4CBDCDCD2EFD2A uses weak digest algorithm (SHA1)

when running apt-get update .

Percona .deb packages sign with a key that uses analgorithm nowconsidered weak. Starting with the next release, Debian and Ubuntu packages aresigned with a new key that uses themuch stronger SHA-512 algorithm. All future package release will also contain the new algorithm.

You’ll need to do one of the following in order to use the new key:

If you installed the Percona repository package as describedhere, this package isautomatically updated to a new package version ( percona-release_0.1-4 ). This package currently contains both the old and new keys. This helps make the transition easier (until all packages are signed with the new key). Install the new Percona repository package as described in theinstallation guide. Manually download and add the key from either keys.gnupg.net or keyserver.ubuntu.com by running:
apt-key adv --keyserver keys.gnupg.net --recv-keys 8507EFA5 or
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8507EFA5

It’s important that you add the new key before the next release. Otherwise the following warning gets displayed:

W: GPG error: http://repo.percona.com xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9334A25F8507EFA5
