Dnfdragora GUI hangs/stuck at 0% refresh on Fedora 42 MATE - "timeout reached while reading from pipe"

Hello,

I’m using a fresh installation of Fedora 42 with the MATE spin. I’m encountering an issue with the dnfdragora graphical package manager.

When I launch dnfdragora, the application window opens and the progress bar for “Refreshing software cache” or similar starts, but it immediately gets stuck at 0% and doesn’t move forward. The application becomes unresponsive, and I have to manually close it (e.g., using xkill or killing the process).

Here’s what I’ve already tried:

  1. I have confirmed that refreshing repositories and updating the system from the command line works perfectly fine. sudo dnf5 upgrade --refresh completes without any errors or issues. This indicates that the core package manager (dnf5) and network connectivity to the repositories are working correctly.
  2. I have run sudo dnf5 clean all multiple times.
  3. I have tried removing and reinstalling dnfdragora and dnfdragora-updater using sudo dnf5 remove dnfdragora dnfdragora-updater followed by sudo dnf5 install dnfdragora dnfdragora-updater. This did not resolve the issue.
  4. I have noticed that this issue might have started or worsened after a recent system update.
  5. Other graphical package managers, like GNOME Software (if installed), seem to work correctly on my system, suggesting the problem is specific to dnfdragora.

When I launch dnfdragora directly from the terminal (dnfdragora), the application window appears and hangs, and the terminal outputs the following messages:

__async_thread_loop(list_fd): timeout reached while reading from pipe.
Terminato

The line __async_thread_loop(list_fd): timeout reached while reading from pipe. seems particularly relevant and indicates a problem with the communication between the dnfdragora GUI and the backend process performing the refresh.

Based on the fact that the CLI works and the terminal output points to a communication timeout, I suspect this might be a bug in dnfdragora, its underlying UI library (libyui), or their interaction with dnf5 on Fedora 42, possibly related to a recent update.

Has anyone else experienced this specific issue on Fedora 42 MATE? Are there any known workarounds or is this a recognized bug?

Any help or insight would be greatly appreciated.

Thank you!
