Docker image issue about community-skeleton

[I-Am-Skoot]

I ran into the same issue, so I sent the output of the build to a log file here are the highlights.

of note:
step 8 GPG key retrieval times out.

#8 125.4 Processing triggers for dbus (1.12.2-1ubuntu1.4) ...
#8 416.9 Error: retrieving gpg key timed out.

The problem is that the Dockerfile uses Ubuntu version 18.04, which currently doesn't have support. Therefore, when trying to install PHP 7.4, it fails, and as a result, all packages don't install successfully. You only need to change the Dockerfile to use version 20.04, and it will work. Here is and exaple of Dockerfile
