• Describe the issue
  tcl8 was rebuilt during the f42 mass rebuild, but there never was a released build prior to that. As a compat package for tcl, which is in the process of being upgraded to an incompatible version 9.0, this migration needs to be handled properly, and while work had begun in a side tag (f42-build-side-103615), it is not ready yet. With the merging of f42-rebuild into f42, this is causing conflicts with tcl-8 builds which is breaking ELN builds (at least, and likely future f42 builds) and possibly will start breaking F42 composes as well.

As such, please untag the releng build so that the migration may continue when ready:

koji untag-build -v f42-rebuild tcl8-8.6.15-9.fc42
koji untag-build -v f42 tcl8-8.6.15-9.fc42

• When do you need this? (YYYY/MM/DD)
  Immediately

• If we cannot complete your request, what is the impact?
  F42 and ELN builds, and possibly composes, will continue to break.
