podman build fails with "cp: cannot access '/root/files/mono-6.12.0.147': Permission denied"

Trying to run

./build.sh 3.x mono-6.12.0.147

fails for me in trying to build this container:

STEP 1/4: FROM godot-fedora:3.x-mono-6.12.0.147
STEP 2/4: ARG mono_version
--> 29b0f1a0983

The first few containers seem to build fine:

COMMIT godot-fedora:3.x-mono-6.12.0.147
COMMIT godot-export:3.x-mono-6.12.0.147

This one failing container then in turn seems to cause all the rest of the containers to fail to build:

STEP 1/4: FROM godot-mono:3.x-mono-6.12.0.147

This is on Fedora 34 host, and just freshly pulled in Fedora 34 docker image.

Edit: running with selinux disabled temporarily (sudo setenforce 0) seems to allow the containers to be built correctly.
Fedora has selinux on by default (I think, at least I've never voluntarily followed a guide to enable it) so this repo should be updated to work with it, or explicit instructions should be included in the readme for disabling it.

I confirm, I had a pull request to add a note for this #75, but it wasn't merged.

See also #74.

Something like this can help to notify users about SELinux:

if [ -f /etc/selinux/config ] && [ $(getenforce) == "Enforcing" ]; then
  echo "Cannot build with SELinux status set to Enforcing."
  echo "Please set SELinux status to Permissive with:"
  echo "    sudo setenforce 0"
  exit 1
