Unable to Download Dependencies and Setup Unreal Engine 4.27.0 on Linux

I am encountering an issue while trying to set up Unreal Engine 4.27.0-release on my Linux desktop. The setup script fails to download dependencies and reports a “403 Forbidden” error. Additionally, I am facing issues related to Mono setup during the project file generation phase.
I have been trying to setup Microsoft AirSim, however, I believe I need to use UE 4.27.0, since when I succesfully installed 4.27.2 it would not work.

Every way that I have tried to install 4.27.0-release I am able to install the source code from github, however everytime I time to run ./Setup.sh I get the error code"

~/UnrealEngine1$ ./Setup.sh
Registering git hooks… (this will override existing ones!)
Fixing inconsistent case in filenames.

Failed to download ‘http://cdn.unrealengine.com/dependencies/UnrealEngine-16546836/0115693eb18085175fb3bd9da53e044d46e4b6f4’: The remote server returned an error: (403) Forbidden. (WebException)
Result: 1

I have also tried doing ./Setup.sh --force, which does start the setup up process but does not setup most of the required files, including the entire Binaries directory.

Any guidance would be greatly appreciated, since I am completely lost on what to try next.
