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
Seems a GPU issue, try :
sudo ubuntu-drivers autoinstall
Or (or both) change graphic emulated performance to software if your emulated device allow it.
Had same issue with linux mint android studio .. Hope it will help.
