To verify whether the process is running in the background, you can also use the
And there you have it!
Did you know that you can use an ISO file as a local repository?

This can be a lifesaver for Enterprise servers where you deal with critical situations on the daily basis.
And for that, we have a detailed guide on how you can use the Rocky Linux ISO as a local repository:
