I think that it is, quite a good one, even:

- Determine the command that has to be run by the algorithm above.

This does most of the work a user would have to figure out what has to be installed on their system.

- Ask whether to run the command automatically.

This allows the “software should never install dependencies by itself” crowd to say no and figure out further steps, while allowing people who just want it to work to get on with their task as quickly as possible (who do you think there are more of?).

I think it would be fine to print out the command and force the user to run it themselves, but it would bring little material gain at the cost of some of your users’ peace (“oh no it failed, what is it this time ...”).
