How to remove installed elpa package

Question

This is strange, the list-packages buffer shows \"available\" as the status for some packages that are actually installed. Shouldn\'t that column show \"install

Answer 1

The package menu shows all known versions of a package.

As such, you may see an installed package listed as available as well, for instance, if there is a newer version of the same package available, or if the same package is available from different archives.

To delete such a package, simply scroll down in the list, or use C-s to search for occurrences of the package. Once you find the installed version of the package, press D to mark the package for deletion; if this fails, press d. You should see a D mark in the left before the package name. Press x to execute the action and actually delete the package.
