无法在 Ubuntu 20.04 上安装 bazel - EXPKEYSIG 无效

Question

我按照https://docs.bazel.build/versions/master/install-ubuntu.html#install-with-installer-ubuntu上的说明进行操作

并尝试在 Ubuntu 上安装 bazel。

当我运行第 2 步时： sudo apt update && sudo apt install bazel

我明白了：

有人知道如何解决这个问题吗？

Answer 1

Bazel Ubuntu PPA 密钥已过期。

来自https://github.com/bazelbuild/bazel/issues/11470#issuecomment-633205152：

您可能必须使用新密钥手动更新您的 apt 密钥环：

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

尝试使用 Bazelisk 安装 Bazel，如下所示：

1. cd ~
2. wget https://github.com/bazelbuild/bazelisk/releases/download/v1.6.1/bazelisk-linux-amd64
3. chmod +x bazelisk-linux-amd64
4. sudo ln -s ~/bazelisk-linux-amd64 /usr/bin/bazel
5. 试运行：bazel version
