@adityapruthi01 please try with 4.6 instead.

@Ryanf55 can you tell at a glance what might have gone wrong here?

[adityapruthi01]

Thanks for your reply.
Is there any specific command to install 4.6?
I have just followed this https://ardupilot.org/dev/docs/building-the-code.html#setting-up-the-build-environment

Kindly revert.
