ATTENTION: Read if you cannot install from deb feed: The APT distribution key has expired today

The key listed on the instruction page

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

specifically, this file:

wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB

is old, and has just expired. There will be a million failures; do not panic; I hope Intel will fix that very quickly.

Could you try the package once again right now? The packages should be re-signed.

Sure, tested and found no problems. 'apt update' passed (so that the Release file signature is ok). I also installed, just for testing, intel-psxe-common-2018.0-033, intel-psxe-common-2019.2-057, intel-psxe-common-2019.5-075 -- all three packages checked out good, too, no complaints from dpkg.

Thanks for the update!
