Hi,

When I follow the steps on https://dev.mysql.com/doc/mysql-apt-repo-quick-guide/en/#apt-repo-fresh-install to install on Ubuntu, I'm getting this error:

Err:4 http://repo.mysql.com/apt/ubuntu jammy InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9D769D5183E7DDC8

I'm using the latest version of the apt-config repo (mysql-apt-config_0.8.36-1_all.deb), which still installs an older key:

$ gpg --show-keys /usr/share/keyrings/mysql-apt-config.gpg
pub rsa4096 2023-10-23 [SC] [expires: 2027-10-23]

uid MySQL Release Engineering <mysql-build@oss.oracle.com>
sub rsa4096 2023-10-23 [E] [expires: 2027-10-23]

There isn't a new key available either at https://repo.mysql.com/ (the latest is https://repo.mysql.com/RPM-GPG-KEY-mysql-2025 which is the old key).

Was there a key rotation yesterday? Will there be an update to the apt-config repo soon for the new key? This is blocking new repo-based installs on Ubuntu.
