you cannot delete an extension that I know of.
Sorry, typo on my end, that is the url that i'm using. I get the same error
I notice also that there is a space between the o and the t in hotfix? might just be a paste issue though.
here is my URL that works:
the only other thing I would possibly look at is whether VSCANMAC9000 is definitely seen as a package or an extension, I had mistakenly thought that this command would bring in extensions and it doesn't.
Yeah that URL works for me if i try and remove a "Install" package, but not any "Hotfix" package. I know its a valid package because the repository.findpackage returns it
