I obtained the rawhide image of Fedora from Docker using ‘fedora:rawhide’ and proceeded with the following steps:

  1. Updated the DNF package manager using ‘yum update -y dnf’.
  2. Attempted to install the curl packages using ‘yum install -y curl’.

However, I encountered the following error:

[root@020f0f5fdc35 /]# yum install -y curl info
Traceback (most recent call last):
  File "/usr/bin/yum", line 61, in <module>

This issue began occurring today; it was functioning correctly yesterday. This is the full log from the starting the container

Added dnf, fedora-rawhide

It looks like something is broken with the latest dnf update.

Can we ask why you are using rawhide please? It is only meant to be used for testing by the community and is not considered “stable”:

If you’re helping with testing, you should contact the Fedora QA team who will probably know what is going on here:

(Ask Fedora is meant for stable releases of Fedora only, since we cannot continuously test rawhide to keep up with its status)

(Edit: we could move this to the Project Discussion category which is more appropriate for rawhide?)

Hello Ankur,

I represent the Artifactory team. We’re currently testing the compatibility of rawhide with Artifactory to identify any potential issues in advance. Rest assured, I’ll follow up with the fedora-qa team regarding this matter.

Best regards,
Krishna

It’s not generally safe to do selective updates, especially in Rawhide; you should really update the entire system or container. Strictly speaking there’s probably a missing or insufficiently strict dependency here, but it’s not an uncommon thing to happen. The new libdnf is likely built against something else you did not update; from a quick google it looks like that is a relatively new function in glib.

edit: oh, looking at your post carefully, you may well have a rather outdated base image. the Fedora images in the docker registry are updated only infrequently, because we cannot update them fully automatically (docker require some manual steps). We strongly recommend getting Fedora images from quay.io or registry.fedoraproject.org instead, e.g.:

FROM quay.io/fedora/fedora:rawhide

It could help if glib would use versioned symbols like glibc and some other libraries do. That way rpm can generate dependencies which would have pulled in the new version of the glib libraries.

Note I am facing a similar issue with the reported one on this thread. I filed it to the Fedora Bugzilla ticket: 2265336 – ImportError: /lib64/libdnf.so.2: undefined symbol: g_once_init_enter_pointer.
