In my opinion “--only-substitutes” should stop and report a list. If it continued without complaining there could be problems: * partial upgrades could leave the profile in an unusable state * an attacker could use this to trick a user into thinking that they have all available updates On the other hand, it would make “--only-substitutes” less usable, because to actually perform work one would have to deal with the failure case. I suppose it could download the substitutes but not build a new profile and report an error at that point. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
