我正在按照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。
当我运行步骤2时：
sudo apt update && sudo apt install bazel
我得到：

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