This does not happen on the first time sync but only from the second time onwards.

Remote:

Pulp versions:

            "version": "3.13.0"
        },

            "component": "deb",
            "version": "2.13.0"
        }
    ]

I don't notice anything wrong when I am fetching the packages but I am not sure if I should be worried about this error.
