gpg keys failure prevent yum install of Intel libraries

[Barak__Ron]

To install intel-daal-core-2018.1-163 on CentOS, I used these two repo files:

/etc/yum.repos.d/intel-mkl.repo:

[intel-mkl-core-2018.1-163] 
name='Intel(R) Intel Math Kernel Library' 
baseurl=https://yum.repos.intel.com/mkl 
enabled=1 
gpgcheck=1 
repo_gpgcheck=1 
gpgkey=https://yum.repos.intel.com/mkl/setup/PUBLIC_KEY.PUB 
debuglevel=10 
enabled=1

/etc/yum.repos.d/intel-daal.repo:

[intel-daal-core-2018.1-163] 
name='Intel(R) Data Analytics Acceleration Library' baseurl=https://yum.repos.intel.com/daal 
enabled=1 
gpgcheck=1 
repo_gpgcheck=1 
gpgkey=https://yum.repos.intel.com/daal/setup/PUBLIC_KEY.PUB 
debuglevel=10 
enabled=1

But, from this morning, the yum install command (sudo yum install intel-daal-core-2018.1-163) fails with:

failure: repodata/repomd.xml from intel-mkl-core-2018.1-163: [Errno 256] No more mirrors to try. https://yum.repos.intel.com/mkl/repodata/repomd.xml: [Errno -1] Gpg Keys not imported, cannot verify repomd.xml for repo intel-mkl-core-2018.1-163

However, if I stop checking the gpg keys, namely - I change the repo files to:

[intel-mkl-core-2018.1-163] 
name='Intel(R) Intel Math Kernel Library' 
baseurl=https://yum.repos.intel.com/mkl 
enabled=1 
gpgcheck=1 
repo_gpgcheck=0 
#gpgkey=https://yum.repos.intel.com/mkl/setup/PUBLIC_KEY.PUB 
debuglevel=10 
enabled=1 


[intel-daal-core-2018.1-163] 
name='Intel(R) Data Analytics Acceleration Library' 
baseurl=https://yum.repos.intel.com/daal 
enabled=1 
gpgcheck=0 
repo_gpgcheck=0 
#gpgkey=https://yum.repos.intel.com/daal/setup/PUBLIC_KEY.PUB 
debuglevel=10 
enabled=1

And do:

sudo yum clean all ; sudo rm -rf /var/cache/yum

Then sudo yum install intel-daal-core-2018.1-163 is successful.

Googling didn't find any notice from Intel that they changed something.
Does anyone know what's the reason for the yum failure of gpg keys?

Same problem in Debian/APT feed. The key has expired today. Hope they'll fix it on Monday.

Could you try the package once again right now?

Seems the gpg keys problems for the daal/mkl libraries is fixed.

on "Tue Oct  1 09:48:23 PDT 2019" - I executed sudo yum install intel-daal-core-2018.1-163 --downloadonly -y without any errors.[1]

Thanks, Gennady.

[1] also no errors for sudo yum install intel-mkl-core-2018.1-163 --downloadonly -y
