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.  
Setting up Mono  
Checking dependencies…  
Updating dependencies: 0% (0/64459)…  
Failed to download ‘[http://cdn.unrealengine.com/dependencies/UnrealEngine-16546836/0115693eb18085175fb3bd9da53e044d46e4b6f4](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.

Hi,

do you already got a solution for this? I have the same problem and don’t know how to fix it.

All I found out was that they had a problem with the Commit.gitdeps.xml file

([https://forums.unrealengine.com/t/upcoming-disruption-of-service-impacting-unreal-engine-users-on-github/1155880](https://forums.unrealengine.com/t/upcoming-disruption-of-service-impacting-unreal-engine-users-on-github/1155880))

But even after I updated the file, it doesnt work.
