When running apt-get upgrade I get this error:
Reading package lists… Done W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://repo.percona.com trusty InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 9334A25F8507EFA5
W: Failed to fetch http://repo.percona.com/apt/dists/trusty/InRelease
W: Some index files failed to download. They have been ignored, or old ones used
This issue with Percona is known and documented here - https://www.percona.com/blog/2016/10/13/new-signing-key-for-percona-debian-and-ubuntu-packages/
When will a fix be incorporated into EasyEngine?
