-a second system
-deleting pckcache db and . dcap-qcnl
-factory reset
-fresh reinstallation of OS and set up env from scratch
-SGX DCAP version 1.21, 1.21 reproducible, 1.22 reproducible

An e068 is due to in invalid signature as per

SGXDataCenterAttestationPrimitives/QuoteGeneration/quote_wrapper/common/inc/sgx_ql_lib_common.h

Line 147 in aa239d2

SGX_QL_RESULT_INVALID_SIGNATURE = TEE_MK_ERROR(0x0068), TEE_RESULT_INVALID_SIGNATURE = TEE_MK_ERROR(0x0068), ///< Invalid signature during quote verification

, but i really don't understand why i am getting this weird error.
