Your source resolves to the version 1 of the feed which doesn’t seem to work with -AllVersions
(I filed an issue: https://github.com/NuGet/NuGetGallery/issues/563)
Using the V2 feed works for me:
get-package -ListAvailable -AllVersions -filter nunit -source https://nuget.org/api/v2/
But note that -filter
is not for a specific package, but more like a search term.
As a workaround, I’d use tab autocomplete to get the versions list of a specific package:
install-package -source https://nuget.org/api/v2/ -id nunit -version <tab>
