We have removed the files for libsgx-enclave-common-dev from the setup scripts, but we don't explicitly remove them from an existing OE installation when we upgrade with oe-contributors-acc-setup.yml. With that we have both libsgx-enclave-common and libsgx-enclave-common-dev on the system. This causes random failures while calling enclave_delete in the enclave common library.

AFAIK lib-sgx-enclave-common-dev package installs lib-sgx-enclave-common.so which is a (symbolic?) link to the lib-sgx-enclave-common.so.X shared library installed by lib-sgx-enclave-common package.

Having both lib-sgx-enclave-common and lib-sgx-enclave-common-dev packages installed ought not cause issues.

Can you let us know what ldd libsgx-enclave-common.so shows on the failing system?

I have cured the system by manually removing the lib-sgx-enclave-common-dev package. My observation is that after I done that, the enclave_delete doesn't fail randomly anymore.

It's hard to go back to history and run the ldd command. But I think removing the redundant package in the ansible script is a prudent thing to do. Not urgent though, unless another user complaints the same issue.

@jxyang
Good to hear that the problem is resolved.
We are however curious about the root cause since lib-sgx-enclave-common-dev is designed to coexist with lib-sgx-enclave-common.

Can you please reinstall lib-sgx-enclave-common-dev package and see if the issue starts occuring?
