I was trying to install SDK and Emulator without the Andriod studio on Ubuntu 20.04. But got stuck at this error.
E0520 11:06:29.866803544 5261 socket_utils_c
I got the solution from this article:
So in order to fix this, I just disabled the Camera by switching the option from Emulated to None and that was all.
Emulated
None
Don't ask why this works, but it seemed to solve it for me.
