我正在尝试使用 Ansible 在 vagrant 上测试 PHP 7.0 安装并收到此错误：
TASK [php-cli : Install php7.0-cli package] *****************************************************************************

尝试删除 ppa：
vagrant@jessie:~/ansible/infra/deployment$ sudo add-apt-repository --remove ppa:whatever/ppa
Cannot access PPA (https://launchpad.net/api/1.0/~whatever/+archive/ppa) to get PPA information, please check your internet connection.

我该如何处理这个错误？
答案1
您可以手动删除此 ppa：
sudo rm /etc/apt/sources.list.d/ansible-ansible-jessie.list
然后：
sudo apt-get update
如果您想使用此 ppa，请添加trusty代号而不是jessie：
sudo nano /etc/apt/sources.list.d/ansible-ansible-jessie.list
然后添加以下行：
deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main
然后运行sudo apt-get update，查看接受的代码名安西布尔 PPA，如您所见，jessie 目录未列出。
