Notes
Installing Lua is not part of this extension.
Furthermore, the task requires the use of the lua command.
Thus, you are responsible for the Lua installation and that the lua command can be accessed.
The following section describes how to install Lua on Ubuntu.
Something like this is necessary if you use a Microsoft-Hosted Pipeline, because Lua is not installed by default.
Ubuntu Installation
steps:
- script: sudo apt-get install lua5.4
