Pulp

I was unsure whether to open this as an issue here, with Nectar or with RPM Support so defaulting to top level.

To reproduce:

pulp-admin rpm repo create --relative-url test --feed http://www.gtlib.gatech.edu/pub/centos/6.6/os/x86_64/ --repo-id test
pulp-admin rpm repo sync run --repo-id test
[...]
Downloading distribution files...

Distributions: 3/4 items

Errors encountered during distribution sync:

File: http://www.gtlib.gatech.edu/pub/centos/6.6/os/x86_64/images/boot.iso
Error
Code: None
Error Message: None

This appears to be because Nectar is using requests.py which does not support ftp. From my logs:

This is likely a related issue - https://pulp.plan.io/issues/197

I worked around this by finding another mirror that didn't point to their ftp server to download this iso.
