运行更新时出错：GPG 错误：http://repository.spotify.com stable InRelease

Question

当我更新时，出现此错误：

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://repository.spotify.com stable InRelease: Seuraavia allekirjoituksia ei voinut varmentaa koska julkista avainta ei ole saatavilla: NO_PUBKEY 13B00F1FD2C19886 

W: Tiedoston http://ppa.launchpad.net/openshot.developers/ppa/ubuntu/dists/trusty/main/binary-i386/Packages nouto ei onnistunut  404  Not Found

W: Some index files failed to download. They have been ignored, or old ones used instead.

我应该怎么办？

Answer 1

看来 Spotify 已经更改了密钥。您可以通过在终端中运行以下命令来解决此问题：

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys D2C19886

参考官方更新和安装指示。
