[bking@apt1002] /srv/wikimedia$ sudo -E reprepro -C thirdparty/opensearch2 copy trixie-wikimedia bookworm-wikimedia opensearch
Warning: replacing 'opensearch' version '2.19.4' with equal version '2.19.4' in 'trixie-wikimedia|thirdparty/opensearch2|amd64'!
Exporting indices...
Could not find any key matching '9D392D3FFADF18FB'!
ERROR: Could not finish exporting 'trixie-wikimedia'!
This means that from outside your repository will still look like before (and
should still work if this old state worked), but the changes intended with this
call will not be visible until you call export directly (via reprepro export)
Changes will also get visible when something else changes the same file and
thus creates a new export of that file, but even changes to other parts of the
same distribution will not!
There have been errors!
```

Possible caused by running:
`sudo -E reprepro -C component/opensearch2 copy trixie-wikimedia bookworm-wikimedia` WITHOUT `opensearch` at the end?

I also had to delete some HAProxy packages before adding the opensearch package, approved by Traffic in P90343
