ubuntu - 由于 spotify 存储库，sudo-apt get update 失败

Question

我一直在尝试运行 sudo apt-get update它不断吐出一个错误，它无法获取 http://repository.spotify.com/dists/stable/InRelease .输出如下:

现在有什么方法可以完全摆脱 spotify 存储库吗？或者更新它？我想不通。

Answer 1

在输出中确定以下值，您现在看到的是 供引用

NO_PUBKEY 11111111111

然后将其添加到以下命令中，在本例中为 11111111111

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 11111111111

最后

$ sudo apt update

它对我有用，这是帮助我的来源，我希望它对你有用。
