Description of problem: Trying to build images using `DOCKER_BUILDKIT=1` is not functional (block in the first step). Version-Release number of selected component (if applicable): Fedora 30, update-testing, build moby-engine-18.09.7-4.ce.git2d0083d.fc30 https://bodhi.fedoraproject.org/updates/FEDORA-2019-572b06a0f7 How reproducible: Start in an empty directory with a simple Dockerfile: FROM fedora USER root RUN useradd -u 1000 foo Try to build it with the following command: DOCKER_BUILDKIT=1 docker build --no-cache . docker stays in the RUN step and never ends (the problem is not command specific, I reproduced the problem with a COPY command). If I run the same steps without buildkit, as: docker build --no-cache . Everything works fine, but of course, I can not use buildkit features. The build kit build works fine with the current fedora30 package: moby-engine-18.06.3-2.ce.gitd7080c1.fc30.x86_64 I encountered the same buildkit issue with a rebuild of the current rawhide package: moby-engine-18.09.8-1.ce.git0dd43dd.fc31.src.rpm
Thanks for the report. I reproduced the problem and I'm working on it.
Just tried to rebase the package on docker-ce 19.03.2. And the problem is still there. So I suppose it's something fedora specific. I noticed that when stopping the build with ctrl-C, there is a runc process that keeps running. I don't tried to investigate more, but could take time if needed. How can I help to get this bug solved ? Any tip, where to search or stuff to try ?
Just updated to Fedora 31. Same problem here.
Should be fixed in moby-engine 18.09.8 (available for f31, f32 and rawhide). Please re-open if you still encounter the issue.
Oops, finally reproduced it again.

Sorry for the delay. Quickly tested it today, and seems to be working as expected; thanks. I'll make further tests during the day and update bodhi.
Thank you for your reply. I'll wait for your Bodhi feedback before pushing it to stable.
Working with that version since yesterday; so issue found; karma updated on bodhi. Problem solved for me, thanks.
