Hi there!

You can not use apt-get install commands directly on the App Platform.

Instead, all that you need to do is to create an Aptfile and add the dependencies that you want to install.

Here, is an example repo that I’ve put together with an Aptfile:

Note that the run command should not contain any apt-get install commands as well, the App Platform will automatically install the package listed in the Aptfile.
