I want to install the package running:

M-x package-install RET markdown-mode RET

And I get the following error

package-install-from-archive: https://melpa.org/packages/markdown-mode-20180904.1601.el: Not found

Which is true, since doing via Firefox I get 404 error.

I have the following version of Emacs:

GNU Emacs 26.1 (build 1, x86_64-pc-linux-gnu, GTK + Version 3.22.30)
  of 2018-07-05

How can I install it?

It's trying to download an older version of the package. Emacs keeps a cache the list of available package versions on every command, to save time and bandwidth. It refreshes the list when you open the package list with M-x list-packages or when you press r (package-menu-refresh) on the list. If you use M-x package-install directly, you may need to refresh the list manually with M-x package-refresh-contents before calling package-install.
