wine 的签名验证错误 - 索引文件下载失败 - 更改镜像无济于事

Question

当我sudo apt-get update收到如下所示的错误时。

W: An error occurred during the signature verification. 
The repository is not updated and the previous index files will be used. 
GPG error: https://dl.winehq.org/wine-builds/ubuntu bionic InRelease: 
The following signatures couldn't be verified
 because the public key is not available: NO_PUBKEY 76F1A20FF987672F
W: Failed to fetch https://dl.winehq.org/wine-builds/ubuntu/dists/bionic/InRelease
The following signatures couldn't be verified
 because the public key is not available: NO_PUBKEY 76F1A20FF987672F
W: Some index files failed to download. They have been ignored, or old ones used instead.

所以我继续按照这个 Ask Ubuntu answer 的建议更改我的镜像。然后我重新启动计算机。当我sudo apt-get update.

让我们尝试重新安装密钥。

$ wget -nc https://dl.winehq.org/wine-builds/Release.key && sudo apt-key add Release.key
File ‘Release.key’ already there; not retrieving. OK

我也可以ping -c3 archive.ubuntu.com，我的丢包率是 0%。我还需要做什么？

Answer 1

截至 2018-12-19 08:07，这里winehq.key提到了一个新的密钥文件。

下载新的存储库密钥并将其添加到受信任的密钥列表中：

cd /tmp
wget -nc https://dl.winehq.org/wine-builds/winehq.key
sudo apt-key add winehq.key
sudo apt update

正如@jason-hunter 在评论中提到的，apt update会询问您是否接受存储库中的更改，而apt-get update将显示错误并失败。

Answer 2

请注意，添加新的密钥文件后，最好使用apt update而不是apt-get update，因为它会提示您接受更改。

所以完整：

wget -nc https://dl.winehq.org/wine-builds/winehq.key && sudo apt-key add winehq.key && sudo apt update

Answer 3

检查https://dl.winehq.org/wine-builds/，有一个新文件winehq.key。尝试使用它，因为它的指纹似乎与错误匹配：

# curl -sL "https://dl.winehq.org/wine-builds/Release.key" | gpg --dry-run --import --verbose
gpg: pub  rsa4096/818A435C5FCBF54A 2015-11-23  Sebastian Lackner (WineHQ packages) <sebastian@fds-team.de>
gpg: Total number processed: 1
# curl -sL "https://dl.winehq.org/wine-builds/winehq.key" | gpg --dry-run --import --verbose
gpg: pub  rsa3072/76F1A20FF987672F 2018-12-10  WineHQ packages <wine-devel@winehq.org>
gpg: key 76F1A20FF987672F: 1 signature not checked due to a missing key
gpg: Total number processed: 1

Answer 4

这个命令对我有用：

wget -nc https://dl.winehq.org/wine-builds/winehq.key && apt-key add winehq.key
