Answer 1

Last version of MKL that supports Ubuntu 14.04 is MKL2018

Post that, MKL doesn't support Ubuntu 14.04 anymore.

Answer 2

the problem here is related to installation. MKL's system requirements contain only those OS's which are validated by this version of mkl. It means that if you copy mkl's binaries to requested OS, we expect MKL will work on Ubuntu v14. The same questions were regarding RH5 support, as an example.
