Trying to install MySQL and Workbench on Ubuntu 22.04, issues with GPG key. When running update to see if my changes have had effect I persistently get:
: An error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://repo.mysql.com/apt/ubuntu jammy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B7B3B788A8D3785CW: Failed to fetch http://repo.mysql.com/apt/ubuntu/dists/jammy/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B7B3B788A8D3785CW: Some index files failed to download. They have been ignored, or old ones used instead. I have removed and reinstalled the public key to the APT keyring, fetched the key directly from keyserver, deleted and reinstalled the repository.Any takers? Could really use some advice...
