我是 Ubuntu 新手,安装 Atom 后遇到了一些问题。第一次安装失败,删除了它。第二次安装成功,运行起来了。
但是现在运行时sudo apt-get update
出现以下错误:
W: GPG error: https://packagecloud.io/AtomEditor/atom/any any InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4C6E74D6C0A35108
W: The repository 'https://packagecloud.io/AtomEditor/atom/any any InRelease' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
我该如何解决这个问题?
