Not working:

http://localhost:8624/api/packages/my-debian/upload?purl=pkg%3Adeb%2Fnano%409.0-1%3Farch%3Damd64%26distro%3Dwtf
Write-Error: Upload failed for pkg:deb/nano@9.0-1?arch=amd64&distro=wtf Distribution must be specified when adding a Debian package.

So the actual distribution doesn't matter since it's already part of the purl but upload fails when omitted.

It looks like the HTTP Endpoint documentation for the pgutil packages upload command was not accurate. A purl is not used here. I've updated the docs as follows...

To upload a package, simply PUT to the URL with a feed name, an appropriate API Key and a package in either ZIP, JAR or TAR format depending on the value of the Content-Type header.

PUT /api/packages/«feed-name»/upload[/«package-file-name»]

The «package-file-name» part of the URL is only required for the PyPI and RPM feed types, while Debian feeds will require a distribution argument and an optional component. See the corresponding upload package method on ProGetClient.cs for the most accurate and up-to-date pgutil and HTTP endpoint argument mapping.

Hope that helps!
