Hello,

Thanks for your question. from the engineer's advise. 

1. You may try again. The issue might have gone already. And if it’s possible, try to find out the exact date and time when the issue happened.
2. If the issue is still reproducing on the your side, pls check if you use any proxy servers for internet access. Also it would be great to download the following files manually and send us MD5 or SHA256 the checksums:
   1. https://apt.repos.intel.com/mkl/dists/all/InRelease
   2. https://apt.repos.intel.com/mkl/dists/all/Release
   3. https://apt.repos.intel.com/mkl/dists/all/Release.gpg
   4. https://apt.repos.intel.com/mkl/dists/all/main/binary-all/Packages
   5. https://apt.repos.intel.com/mkl/dists/all/main/binary-all/Packages.bz2
   6. https://apt.repos.intel.com/mkl/dists/all/main/binary-all/Packages.gz
   7. https://apt.repos.intel.com/mkl/dists/all/main/binary-amd64/Packages
   8. https://apt.repos.intel.com/mkl/dists/all/main/binary-amd64/Packages.bz2
   9. https://apt.repos.intel.com/mkl/dists/all/main/binary-amd64/Packages.gz
   10. https://apt.repos.intel.com/mkl/dists/all/main/binary-i386/Packages
   11. https://apt.repos.intel.com/mkl/dists/all/main/binary-i386/Packages.bz2
   12. https://apt.repos.intel.com/mkl/dists/all/main/binary-i386/Packages.gz

Beside this, the engineer team still do more testing on this issue to see if they can reproduce from their side. 

Thanks,

Alice

Thank you, the problem have gone away.

And i finally see some Facebook container build pipelines (for open source projects) got finally healthy about 2-3 days ago. They are using MKL widely so i had to work using patched downstream with pre-downloaded MKL binaries several weeks. I don't know how much users were affected, but don't think there were a lot, its experimental stuff.

This is (not only) example: https://hub.docker.com/r/wav2letter/wav2letter/tags, they had a delay in image update related to commits history about a month but recently released new one.

Thank you for resolving issue again.
