【问题描述】：
我按照docs中指定的步骤：
git clone -b 4.25 git@github.com:EpicGames/UnrealEngine.git
导致：
Cloning into 'UnrealEngine'...
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
所以我找到了一种解决方法，按照here 的说明将我的 github 帐户与 EpicGames 连接起来。然后我 fork UnrealEngine repo 这是一个私人仓库，除非您按照前面指定的方式连接您的 github 帐户，否则您无法访问它。然后我克隆了 fork：
git clone --depth 1 https://username:token@github.com/username/UnrealEngine.git
导致
Cloning into 'UnrealEngine'...

./GenerateProjectFiles.sh
make
在构建的后期阶段出现错误之前，它工作得非常好，如下所示。你可以查看完整的构建日志here

Building ThirdParty libraries
If you don't see SUCCESS message in the end, then building did not finish properly.
In that case, take a look into /content/UnrealEngine/Engine/Build/BatchFiles/Linux/BuildThirdParty.log for details.
No third party libs needed to be built locally
