Encountered Errors from Client Application Related to Intel® Enhanced Privacy ID (Intel® EPID) When Performing Remote Attestation

1. Installed the Intel® Software Guard Extensions (Intel® SGX) SDK for Linux*, Linux SGX driver, and PSW individual components according to these instructions.
2. Ran the sgx-ra-sample or other remote attestation application.
3. Received any of the following errors after running the client (other errors are possible):

1. Access the Intel® SGX PSW libraries following one of two methods:
   • Configure access to Intel's apt repository as detailed in page 11 of Intel® SGX Installation Guide for Linux*

     $ echo 'deb [arch=amd64] https://download.01.org/intel-sgx/sgx_repo/ubuntu focal main' | sudo tee /etc/apt/sources.list.d/intel-sgx.list ; wget -qO - https://download.01.org/intel-sgx/sgx_repo/ubuntu/intel-sgx-deb.key | sudo apt-key add - ; sudo apt-get update

   • Build a local repository
      
2. Install all components of the Intel® SGX PSW:
   $ sudo apt-get install libsgx-launch libsgx-urts libsgx-epid libsgx-quote-ex libsgx-uae-service
3. Run sudo apt list --installed | grep sgx to ensure that you have the latest version of the PSW packages.

The instructions for installing the Intel® Software Guard Extensions (Intel® SGX) PSW are missing libsgx_uae_service but it is required.
