Hello,
I want to run the Quote Generation Example from Github.
However when running ./app I always receive this error:
Step1: Call sgx_qe_get_target_info:[get_platform_quote_cert_data ../qe_logic.cpp:378] Error returned from the p_sgx_get_quote_config API. 0xe065
Error in sgx_qe_get_target_info. 0xe065
The system uses Ubuntu 22.04.,
sgx_linux_x64_driver_2.11.54c9c4c.bin,
sgx_linux_x64_sdk_2.19.100.3.bin
and the latest PCKIDRetrievalTool.
Thanks in advance for you help.

Hi ChrisCode,
Thank you for your question in Intel® SGX community.
We are looking into this case. Can you provide us the output of these commands to ensure the drivers are loaded correctly:
ls -la /dev/sgx*
Furthermore, we would like to understand if your processor support Flexible Launch Control (FLC) to check if Out-of-Tree driver installation is required. To verify the driver loaded correctly, check that the device shows up in the /dev folder:
ls -la /dev/isgx
Refer Intel® SGX Software Installation Guide for Linux* OS for more information.
Looking forward to hearing from you. Thank you.
Regards,
Ken

Hi,
I removed the OOT driver again, since I read in the installation guide, that it's not recommended for devices, that support FLC. My device (Intel NUC) does.
The output of ls -la /dev/sgx* is:
crw-rw-rw- 1 root sgx 10, 125 Apr 19 14:11 /dev/sgx_enclave
crw-rw---- 1 root sgx_prv 10, 126 Apr 19 14:11 /dev/sgx_provision
crw------- 1 root root 10, 124 Apr 19 14:11 /dev/sgx_vepc
/dev/sgx:
total 0
drwxr-xr-x 2 root root 80 Apr 19 14:11 .
drwxr-xr-x 20 root root 4200 Apr 19 14:11 ..
lrwxrwxrwx 1 root root 14 Apr 19 14:11 enclave -> ../sgx_enclave
lrwxrwxrwx 1 root root 16 Apr 19 14:11 provision -> ../sgx_provision
Is it even possible to use the DCAP example if I am not able to use the DCAP driver?
Since I am on kernel 5.16 I have in-kernel support and installing the DCAP driver results in the following error:
"Can't install DCAP SGX driver with in-kernel SGX support”

Hello ChrisCode,
The in-kernel SGX driver supports DCAP so you do not have to install a separate DCAP driver.
Since you are likely using an insecure certificate for your PCCS service set “use_secure_cert”: false in /etc/sgx_default_qcnl.conf:
// To accept insecure HTTPS certificate, set this option to false
"use_secure_cert": false,

Jesus G.

Sorry, I forgot to close the issue.
The problem was, that there were still some dependencies of my previous OOT driver installation.
After I removed everything, it worked.
Thanks for you help!
