We’re trying to run our builds in a Docker container on the ARM runners. On the below page, all our ARM builds failed with “docker: failed to register layer: Error processing tar file(exit status 1): operation not permitted.”
This used to work fine.
Example: https://travis-ci.com/PQClean/PQClean/jobs/249487649
(All ARM builds on: https://travis-ci.com/PQClean/PQClean/builds/133538480)
It did work in https://github.com/PQClean/PQClean/runs/271074920
I’m seeing the same kind of issue here: https://travis-ci.org/pypa/manylinux/jobs/602580793
Same kind of error: “Error processing tar file(exit status 1): operation not permitted”
Tried to revert to bionic with the same outcome. This also used to work fine: https://travis-ci.org/pypa/manylinux/jobs/602035718
Seeing the same error on aarch64 with bionic and xenial as dist. Installing new packages in a docker container fails with the same error message.
Errors seem to be resolved for me. Can run docker again in aarch64.
It indeed appears to be working again.
I’m disappointed at the lack of communication from Travis though.
Hi @thomwiggers @mayeut @adrianreber
Thanks for your feedback and reporting the issue.
Us not responding in Community Forum quickly doesn’t mean the issues aren’t noticed and put in queue for fixing 
Sorry for longer silence though. I’m very grateful for all information you provide, as it helps us to spot and repair issues more effectively.
We have fixed a couple of configuration and infrastructure related items in last 3 weeks. If these downloads fail again, would you mind to update this thread with information?
All best and happy building!
