Hi, It appears Thunderbird 78.6.0 was never released for CentOS 8.3. Could someone please check on it? Perhaps the Files->c8 section warning is a clue: Warning: This package was configured for automatic debranding, but the changes failed to apply. As a related topic, I have experience building RPM's/mock, superficial git user, but I'm still kinda lost how I might be able to get a .src.rpm out of the current state of https://git.centos.org/rpms/thunderbird/tree/404b3fff4f6bcc2c23e085b4ad2c1eb7d1510712 Any brief / terse tips would be appreciated. I did see Johnny's msg https://lists.centos.org/pipermail/centos-devel/2020-December/075681.html but it doesn't seem to apply to this situation as there is no koji build info. Thanks! Chris
