emacs: package-name is an available obsolete package

Whenever I install a MELPA package, I get this message:

package-name is an available obsolete package

Here is a screenshot of what I mean (first line):

I tried this solution but it did not help.

How to fix it?

Answer 1

That message confused me too. It turns out it's just a poor choice of words for saying that there's a new version available.

Once you update the list of packages with M-x package-refresh-contents, then you can type U x and it will upgrade all installed packages that have a more recent version available.

Once that is done, the message you see when you open the description of an updated package will be:

Package x is installed.
