   It's possible the problem has gone away, since I've been able to get some clean CI runs on a side debug-PR I created (https://github.com/apache/incubator-mxnet/pull/20739).  The only improvement from that work I would suggest is the following line:
   
   https://github.com/apache/incubator-mxnet/blob/705e3d87564a11308ec37c7d0ce07244e14f409c/ci/docker/Dockerfile.build.ubuntu#L103
   
   If there are some mirrors serving up the wrong files, the symptom is that every time one does an `apt-get update` with the repo in the apt repo list, there's a possibility of hitting a bad mirror server and getting the hash-mismatch error.  Thus, I recommend that the docker RUN command that adds the oneapi repo, then installs some packages, should then remove the repo from the apt repo list (seen as "step 5" in the log).  That way, when another docker RUN also does an `apt-get update` (e.g. "step 20" to install tensorrt and cudnn), it won't needlessly reach out to oneapi mirrors.
   
   FYI @josephevans .  If you add the line, you may have to tweek the use of '&&' and '\\' .
