Ubuntu 24.04更新Spotify仓库时遭遇GPG密钥验证失败问题求助

各位大佬求助！我在Ubuntu 24.04系统上执行sudo apt update更新软件源的时候，碰到了Spotify仓库的GPG密钥验证失败的问题，终端里输出了以下错误信息：

Err:4 http://repository.spotify.com stable InRelease  
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6224F9941A8AA6D1
Reading package lists... Done

W: GPG error: http://repository.spotify.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6224F9941A8AA6D1

E: The repository 'http://repository.spotify.com stable InRelease' is not signed.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

有没有大佬能告诉我该怎么解决这个问题呀？感谢感谢！
