Steps to Reproduce:
koji build --scratch f32 kernel-tools-5.5.0-0.rc6.git0.1.fc32.src.rpm

Additional info:
This package is tracked by Koschei. See:

This blocks the Python 3.9 rebuild.

Comment 1 Miro Hrončok 2020-01-21 12:35:44 UTC
This is https://gcc.gnu.org/gcc-10/porting_to.html#common

Comment 2 Ben Cotton 2020-02-11 17:31:24 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle.
Changing version to 32.

Comment 3 Fedora Release Engineering 2020-02-16 04:23:31 UTC
Dear Maintainer,

your package has not been built successfully in 32. Action is required from you.

If you can fix your package to build, perform a build in koji, and either create
an update in bodhi, or close this bug without creating an update, if updating is
not appropriate [1]. If you are working on a fix, set the status to ASSIGNED to
acknowledge this. Following the latest policy for such packages [2], your package
will be orphaned if this bug remains in NEW state more than 8 weeks.

A week before the mass branching of Fedora 33 according to the schedule [3],
any packages not successfully rebuilt at least on Fedora 31 will be
retired regardless of the status of this bug.

Comment 5 Peter Robinson 2020-03-01 09:48:44 UTC
This is actually fixed, there's another issue with s390 (covered in RHBZ 1807781) which is blocking the build ATM.

Comment 6 Miro Hrončok 2020-03-16 18:30:21 UTC
Setting the severity to high.

This package is part of the initial bootstrap sequence. Without it, we cannot proceed with the bootstrap in a Koji side tag.

https://fedoraproject.org/wiki/Changes/Python3.9#Important_dates_and_plan

The current plan is to follow the "ideal point when we can start rebuilding in Koji" -- that is we need to get this bug fixed approximately in 2 months.

That includes potential uncovered bugs in packages that depend on this one.

Please knowledge that you have read this message and that you can dedicate time to fix it. If you know already that you won't be able to fix it by the deadline, please let us know ASAP, so we can allocate resources to do that. Thank You.
