    Related: https://github.com/intel/sgx-software-enable may be able to enable SGX via UEFI stuff for the next reboot, depending on whether your BIOS has explicitly disabled it or left it up to software. The readme for that Intel software explains the possibilities. – Peter Cordes Aug 03 '22 at 23:34

For me the solution was exactly what the error message suggests: to enable SGX in BIOS. I have an HP Elitebook, in the BIOS Security section there is a checkbox:

  • Intel Software Guard Extension (SGX)

I set it to Enable (instead of Disable or Software defined)

You can use sgx software enable to enable Intel SGX on Linux system Where the BIOS supports intel SGX.

This application will enable Intel SGX on Linux systems where the BIOS supports Intel SGX, but does not provide an explicit option to enable it. These systems can only enable Intel SGX via the "software enable" procedure.

I tried it, it works.

I had the same problem, but the SGX option literally did not exist in my BIOS, so it was impossible to change that.

A workaround was to reinstall with the "Minimal installation" option (as opposed to "Normal"), as well as not download updates or install third party software.

The SGX technology has a weakness called Poreshadow or L1TF.

If you are not going to watch 4K bluelay video, turn it off.

In the case that I encountered, I couldn't solve it with "SGX software enable", but it was resolved when I reinstalled my linux and went to BIOS via

systemctl reboot --firmware-setup
