ubuntu - 在 github 操作中安装 Varnish

Question

我尝试在 https://github.com/FriendsOfSymfony/FOSHttpCache/pull/500/ 的 github 操作中安装 Varnish

bash -c 'curl -L https://packagecloud.io/varnishcache/varnish66/gpgkey | sudo apt-key add -'
bash -c 'curl -L "https://packagecloud.io/install/repositories/varnishcache/varnish66/config_file.list?os=ubuntu&dist=focal&source=script" | sudo tee -a /etc/apt/sources.list'
sudo apt-get update
sudo apt-get install -t focal varnish

key 已安装，但 apt-get update 仍然失败

我尝试使用 sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 45DACFFDB8AFA6AA 安装 apt 缺少的 key 它做了一些事情并产生了输出gpg: key 0BAC19E3F6C90CD5: public key "https://packagecloud.io/varnishcache/varnish66 (https://packagecloud.io/docs#gpg_signing) <support@packagecloud.io>" imported (请注意，这里的键不一样 - 对 apt 键不够熟悉，无法判断这是预期的还是有问题的)
知道如何安装它吗？

我在 Varnish Developer Portal 上创建了一个官方教程这解释了如何使用软件包安装 Varnish。
看看https://www.varnish-software.com/developers/tutorials/#installations有关分布的概述。
