Running build.sh, I get the following error:

executor failed running [/bin/sh -c a2enmod userdir && a2enmod php7.3]: exit code: 1

It seems that the step number 8 fails because of missing PHP, even if it seems to be installed at step 2.

Do I miss anything?

I have found the reason of the issue: the Dockerfile references the latest version of Debian, that includes now PHP 7.4.

The Dockerfile should have referenced Debian in this way:
FROM debian:10
