Ubuntu 18.04, install of sgx_linux_x64_driver_1.35.bin silently fails about sgxdatacenterattestationprimitives HOT 4 CLOSED

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 <[email protected]> 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 <[email protected]> Sent: Tuesday, August 4, 2020 12:44 PM To: intel/SGXDataCenterAttestationPrimitives <[email protected]> Cc: Noel Gifford <[email protected]>; Author <[email protected]> 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. 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? — You are receiving this because you authored the thread.

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.

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*. — You are receiving this because you authored the thread.
