W: The repository 'https://storage.googleapis.com/bazel-apt stable InRelease' is not signed.

这个错误提示意味着你的系统无法验证包含 Bazel 的存储库是否是可信的。通常这个问题可以通过更新 apt-get 来解决，例如：

sudo apt-get update

如果更新仍然无法解决问题，你可以尝试手动导入 GPG 签名密钥来验证存储库。你可以按照下面的步骤来完成这个过程：

1. 下载密钥：

$ curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -

2. 添加存储库：

$ echo "deb [arch=amd64] https://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list

3. 更新 apt-get：

$ sudo apt-get update

这些步骤应该可以解决你遇到的问题。

这个错误是由于apt-key无法读取/etc/apt/trusted.gpg.d/目录下的文件，导致无法验证Ubuntu软件源的签名。解决这个问题的方法是：

1. 使用以下命令导入缺失的公钥：

   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 871920D1991BC93C

注意替换上述命令中的871920D1991BC93C为您的错误中所提到的缺失的公钥。

2. 如果上述命令无效，可以尝试使用以下命令：

   sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com

3. 如果上述命令仍然无效，可以尝试手动下载公钥并导入。首先，找到缺失的公钥的ID，例如871920D1991BC93C。然后，使用以下命令下载公钥：

   sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 871920D1991BC93C

最后，使用以下命令将公钥导入系统：

   sudo apt-key add /path/to/downloaded/key

注意替换上述命令中的/path/to/downloaded/key为您下载的公钥文件的路径。

完成上述步骤后，再次运行apt-get update应该就不会出现上述错误了。

这些错误信息表明，apt 在更新软件包时遇到了签名验证失败的问题。这可能是由于存储库中的 GPG 签名已过期或无法验证，或者存储库本身没有签名。

你可以尝试以下方法来解决此问题：

1. 检查你的网络连接是否正常，并确保能够访问相应的存储库。

2. 如果是第一次遇到此问题，你可以尝试更新 apt 的密钥列表。你可以使用以下命令更新密钥列表：

   sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com

3. 如果密钥列表无效，则需要重新导入相关存储库的 GPG 公钥。你可以通过以下命令来导入 GPG 公钥：

   sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys <KEY>

其中，`<KEY>` 是存储库的 GPG 公钥 ID。

4. 如果存储库没有签名，则你需要考虑使用其他可信赖的存储库或联系存储库的维护者寻求帮助。

5. 对于最后两个错误，可能是由于存储库的版本与你的 Ubuntu 版本不兼容所致。你需要检查存储库是否支持你的 Ubuntu 版本，并根据需要将其从源列表中删除。
