Hey, JFYI, we enabled F31 chroots yesterday in Fedora Copr.
The process was surprisingly slow, and a lot of things didn't work
properly during the process. Sorry for that, we'll take a look on how to
minimize the problems for the next runs.
One warning on F31 chroots in copr! The F31 has Python 3.7, while rawhide
has Python 3.8. Since we enabled the F31 chroot pretty late in Copr -
after Python 3.8 landed rawhide - it might happen that you rebuilt your
package against 3.8, and it got later copied into F31 chroot (with the
rest of the packages). If this happened to you, you have non-installable
package in repo.
It is hard hard to work-around now (rebuild is needed), if you have
serious troubles with rebuilding - let us know, we can remove the packages
manually from repositories.
Again, sorry for inconvenience, and happy building!
Pavel
