Getting errors due to expired PGP key for MPI library

  Following the directions at

   https://software.intel.com/en-us/articles/installing-intel-free-libs-and-python-apt-repo

  I downloaded the public key from
   https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB

  previously and kept a copy.  Recently my use of that key started to fail and so I downloaded the key again  and noticed that it now has two values in it, which is odd.

 

  I tried using the public key that has two keys in it and it mostly works -- in some of the zones in GCP this works fine but in others it doesn't.    In one of them that doesn't I did an "apt-key list" and noticed that one of them was expired:

 

pub   2048R/7E6C5DBE 2019-09-30 [expires: 2023-09-30]
uid                  Intel(R) Software Development Products

pub   2048R/1911E097 2016-09-28 [expired: 2019-09-27]
uid                  "CN = Intel(R) Software Development Products", O=Intel Corporation

 

I wasn't able to do an "apt-key del" and so I started over with just the new key.  it shows up with apt-key list as okay:

 

pub   2048R/7E6C5DBE 2019-09-30 [expires: 2023-09-30]
uid                  Intel(R) Software Development Products

 

but I can't do an update:

$ sudo apt-get update

W: GPG error: https://apt.repos.intel.com/intelpython binary/ InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1A8497B11911E097

By the way I tried to email otc-digital-experiences@intel.com as mentioned on https://software.intel.com/en-us/faq and it came back as undeliverable.

I should also add the apt-cache policy:

$ sudo apt-cache policy intel-mpi-2019.5-075
intel-mpi-2019.5-075:
  Installed: (none)
  Candidate: 2019.5-075
  Version table:
     2019.5-075 500
        500 https://apt.repos.intel.com/mpi all/main amd64 Packages

When did you go through these steps?  This should now be resolved, with the updated key pushed out to all geo-replicated keyservers.  You may need to repeat the steps to re-install the key.
