Package Name Filters #1252

Our organization has firewalls that quarantine certain packages that may be flagged as malicious. This returns a 403 error and causes the a repository sync to be incomplete. Currently the workaround is to use the "on_demand" mirror policy but it does not stop the error from happening if the quarantined package is attempted to be installed.

A possible solution would to allow filtering of certain package by name. Otherwise an option to continue past packages that are broken.

The alternatives considered is the workaround mentioned before with changing the mirror policy in the remote object to "on_demand"
