Ubuntu 18.04, install of sgx_linux_x64_driver_1.35.bin silently fails

[nrgifford]

Is installing the 1.35 SGX driver with Ubuntu 18.04 and Kernel 4.15 a supported configuration?

Ubuntu 18.04, Kernel 4.15
Intel SGX Driver 1.20 is installed.

When I attempt to install 1.35 SGX driver, the installation fails with no error message.
Intel SGX Driver 1.20 is still installed.
OE Sample application helloworld now fails.

Rebooting doesn't resolve the failure.

The issue is fixed after
sudo apt update
sudo apt upgrade

SGX driver is still at 1.20.

Not sure why it went silent. Is the regular Ubuntu image or cloud flavor (e.g. Azure flavor)?

4.15 kernel is supported. Did you try to uninstall old driver before installing new one?

It’s a regular Ubuntu image. I think the problem is that I can’t get the v1.20 driver to uninstall. I uninstalled the PSW and all SGX components first. sudo /opt/intel/sgxdriver/uninstall.sh Uninstall failed because the kernel module is in use modinfo intel_sgx filename: /lib/modules/4.15.0-112-generic/updates/dkms/intel_sgx.ko version: 1.20 license: Dual BSD/GPL author: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> description: Intel SGX Driver srcversion: AA38F3484C7F0D7582A954D alias: acpi*:INT0E0C:* depends: retpoline: Y name: intel_sgx vermagic: 4.15.0-112-generic SMP mod_unload signat: PKCS#7 signer: sig_key: sig_hashalgo: md4 lsmod | grep intel_sgx intel_sgx 45056 0 From: Haitao Huang <notifications@github.com> Sent: Tuesday, August 4, 2020 12:44 PM To: intel/SGXDataCenterAttestationPrimitives <SGXDataCenterAttestationPrimitives@noreply.github.com> Cc: Noel Gifford <Noel.Gifford@microsoft.com>; Author <author@noreply.github.com> Subject: Re: [intel/SGXDataCenterAttestationPrimitives] Ubuntu 18.04, install of sgx_linux_x64_driver_1.35.bin silently fails (#124) Not sure why it went silent.

You need stop AESM before uninstalling driver. But uninstalling PSW usually does that. You might have something else using it.
Try use "lsof | grep sgx" to see if running process is using /dev/sgx*.

I was finally able to get the driver removed and the v1.35 driver installed. I don’t know what the issue was, but it’s fixed now. Thanks.
