DNF on Fedora 30 is segfaulting

Fedora 30’s DNF has begun segfaulting. It seems to have started sometime in the last 30 minutes. Non-Fedora images seem unaffected.

It always stops in the same place. Here is an execution log:

#!/bin/bash -eo pipefail
dnf install -y git cmake make gcc-c++

Hi there, welcome to our community!

Could you provide the specific image that you are using?

Hi Paul. Looks like this has happened before to Fedora. Can you give the steps in this StackOverflow answer a try and see if they help? https://stackoverflow.com/a/45173939/335583

Hi Lev and Joe, thank you for the welcome!

This issue appears with the fedora:30 image.

It looks like this is an upstream issue with the fedora:30 Docker image, as the following Dockerfile will reproduce the issue:

FROM fedora:30
RUN dnf update

As for the StackOverflow question, the steps they suggest do not resolve the issue.

I tried. :smile: Glad you were able to isolate the issue.

Thanks again. :slight_smile:

Okay, this issue is due to a bug in librepo-1.9.6-1 that is fixed in librepo-1.9.6-2. Hopefully the fedora:30 image on Docker Hub will be updated soon with this new version.

In the meantime, if someone cannot wait and would like the fedora:30 image working immediately, the steps outlined in this post can be added to your .circleci/build.yml file and should resolve the issue: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/H5BX2XZQFHM7VMAMSMK5VG3DYQYKFUKM/


Thanks for posting the solution!
