linux-kernel - gpg：没有找到有效的 OpenPGP 数据；使用添加存储库

Question

所以当我输入sudo apt-add-repository ppa:elementary-os/stable它返回

 More info: https://launchpad.net/~elementary-os/+archive/ubuntu/stable
Press [ENTER] to continue or ctrl-c to cancel adding it

gpg: keybox '/tmp/tmp9bk0u0va/pubring.gpg' created
gpg: /tmp/tmp9bk0u0va/trustdb.gpg: trustdb created
gpg: key BF36996C4E1F8A59: public key "Launchpad PPA for elementary OS team" imported
gpg: Total number processed: 1
gpg:               imported: 1
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
gpg: no valid OpenPGP data found.

我认为这是我问题的根源只需要一些帮助来解决它
