No update has been submitted for gcc-8.1.1-2.fc28. A buildroot override was submitted for gcc-8.1.1-4.fc28, but it expired already: https://bodhi.fedoraproject.org/overrides/gcc-8.1.1-4.fc28 the only ways for a package to get into the buildroot are to be in a stable update or to have an active buildroot override. So either an update for GCC needs to be sent out and pushed stable before the rebuilds are done, or the buildroot override must be renewed and extended (this could be done, for instance, if we wanted to submit an update of GCC and the rebuilt packages together, after doing the rebuilds). -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/J3AO2RTJH7IJQW3QJS3CTHUXBCGVDW4W/
