The GPG keys listed for the “MySQL 8.0 Community Server” repository are already installed [Fix]

Well, I got this error message “The GPG keys listed for the MySQL 8.0 Community Server repository are already installed but they are not correct for this package” while updating the packages on CentOS 7.9. The complete error message is below:

#yum update
:::::::::::::::::::::::


warning: /var/cache/yum/x86_64/7/mysql80-community/packages/mysql-community-icu- data-files-8.0.29-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79b d29: NOKEY

The GPG keys listed for the "MySQL 8.0 Community Server" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.


Failing package is: mysql-community-icu-data-files-8.0.29-1.el7.x86_64
GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

Solution: The GPG keys listed for the “MySQL 8.0 Community Server” repository are already installed but they are not correct for this package.

To fix this error, import the new GPG key for MySQL.

# rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

Once the new key is imported, update the packages.

# yum update
