Where can I report bugs/RFE for the CentOS Project ?

The CentOS Project actually uses several ticket trackers, so use this list as a filter to know where to report specific bug[s] and/or RFE/requests :

CentOS Stream (all kind of tickets)

see https://wiki.centos.org/FAQ/CentOSStream#Where_do_I_report_bugs.3F

So basically Red Hat Bugzilla

CentOS Infra, CBS, SIGs, mirror, CI, etc

see mail sent to centos-devel list :

Concerned areas :

https://cbs.centos.org (Community BuildSystem, aka koji)
Special Interest Groups requests (for mirror, resources, etc)
https://ci.centos.org (All CI infra ecosystem)
Everything around CentOS Infra (mirror issues, etc)

Use the following tracker for such kind of requests/areas : https:/pagure.io/centos-infra/issues

All the rest (CentOS Linux pkgs, etc)

All other bugs/RFEs not falling into the Stream or Infra categories can be filed in our CentOS Bug Tracker
