It fails due to the dcode package, the URL returns 404, however I checked the URL and it seems to work

@sara-rn dcode is failing in our daily run too: https://github.com/mandiant/VM-Packages/wiki/Daily-Failures I recommend to remove the change in dcode from this PR so that we can merge the other packages and send a PR only for dcode. You will have the same issue for the other packages failing in the daily (dcode.vm, ida.plugin.sigmaker.vm, netcat.vm, and regcool.vm). We need to fix all the failing packages, as we need them to work in the CI to modify them and we need to modify them to move the category to the nuspec. I think some of them are easy to fix (likely just updating a hash).

I am not sure what the issue with dcode is, you may need to do some debugging like testing the package locally and downloading it with CURL. It could be the URL has issues some times (similar to the issue with 010Editor: #1275). In that case, we would need to document the testing we have done in an issue and reach Digital Detective Group Ltd to see if they are able to help (as we did in #1275).

INFO: @sara-rn has implemented these changes using the script https://gist.github.com/sara-rn/9b5d66e5b016e0eb36477ac180d50433 We are splitting the moving of the category to the nuspec in several PRs to avoid issues with the CI (as recommended in the Continuous Integration (CI) Testing Wiki page).
