Ubuntu 20.04 lts Pagoda cannot be installed on nginx

After Ubuntu 20.04 installed the pagoda, the environment was installed, and then when the new site was created, it was displayed that the web service was not installed, and nginx was installed again.

The result still prompts that the web service is not installed.

Solution:

sudo apt-get update

apt-get install libxslt-dev libxml2-dev
