I was trying to look for recipes to lint for you, but it appears we have a merge conflict.
Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Hi @diegoferigo, thanks is great! Do you want to also add the -c option for wget in the same PR? Thanks a lot fixing this

Thanks a lot for your help @diegoferigo . In the case where the download file exists, there is the possibility that the existing file is incomplete. I think possible options are:

• to combine adding the resume options to the wget and curl calls (respectively -c and -C -) as pointed out by @AgrawalAmey with performing the download operation even in the case of the file already existing. (recommended)
• to check additionally that the checksum matches with the desired file‘s checksum, in the branch where the download is not performed. However this requires that the checksum be added from the nvidia page containing the checksums, for the comparison.

Thanks again!
