Comment 2 Jos de Kloe 2026-06-06 21:05:29 UTC
These failing tests are very similar to what I see for the pygrib package. There they are related to a change in the proj package. After updating proj from version 9.7.1 to 9.8.0 some projections changed slightly, causing these image comparisons to fail.

Hello,

This package fails to install and maintainers are advised to take one of the following actions:

 - Fix this bug and close this bugzilla once the update makes it to the repository.
   (The same script that posted this comment will eventually close this bugzilla
   when the fixed package reaches the repository, so you don't have to worry about it.)

or

 - Move this bug to ASSIGNED if you plan on fixing this, but simply haven't done so yet.

or

 - Orphan the package if you no longer plan to maintain it.


If you do not take one of these actions, the process at https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs will continue.
This package may be orphaned in 7+ weeks.
This is the first reminder (step 3) from the policy.

Don't hesitate to ask for help on https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/ if you are unsure how to fix this bug.
