  • That's not a constructive comment. I am asking a question. Commented Oct 5, 2016 at 20:05
  • Also if you are able to find an exact answer to this question in the documentation, please feel free to list it here :) But MikeA actually provided a helpful answer. Thanks for the trolling. Commented Oct 5, 2016 at 20:07
  • Thanks for ignoring advice on how to ask good questions such as catb.org/esr/faqs/smart-questions.html#before. U&L SE is full of questions that could have been avoided if their authors had carefully perused the docs and/or relevant resources in the first place. Commented Oct 5, 2016 at 20:17
  • This question is not answered in the documents. I already checked. But thanks! Commented Oct 5, 2016 at 20:21

  • Yum has various plugins for different things. Check yum documentation or manpages to see what yours are for.

  • Those are not packages, those are the yum repositories you have configured.

  • There are no available security updates, but there is one non-security update available.
