Emacs doesn't want to autoremove packages from elpa because some of them are system packages.

How can I launch autoremove ignoring system packages?

package-delete: Package ‘notmuch-0.26.2’ is a system package, not deleting

I would look at these two. Maybe you could modify package-selected-packages before running package-autoremove.

package-autoremove is an interactive autoloaded compiled Lisp function
in ‘package.el’.

(package-autoremove)

Remove packages that are no more needed.

Packages that are no more needed by other packages in
‘package-selected-packages’ and their dependencies
will be deleted.

[back]  [forward]

package-selected-packages is a variable defined in ‘package.el’.
Its value is
(abyss-theme company-irony company-irony-c-headers flycheck flycheck-irony irony rainbow-delimiters gandalf-theme alect-themes basic-mode elpy org-ac vbasense psvn omnisharp)

Original value was nil

Documentation:
Store here packages installed explicitly by user.
This variable is fed automatically by Emacs when installing a new package.
This variable is used by ‘package-autoremove’ to decide
which packages are no longer needed.
You can use it to (re)install packages on other machines
by running ‘package-install-selected-packages’.

To check if a package is contained in this list here, use
‘package--user-selected-p’, as it may populate the variable with
a sane initial value.

You can customize this variable.

This variable was introduced, or its default value was changed, in
version 25.1 of Emacs.

[back]

Here is the function definition in package.el

;;;###autoload
(defun package-autoremove ()
  "Remove packages that are no more needed.

Packages that are no more needed by other packages in
`package-selected-packages' and their dependencies
will be deleted."
  (interactive)
  ;; If `package-selected-packages' is nil, it would make no sense to
  ;; try to populate it here, because then `package-autoremove' will
  ;; do absolutely nothing.
  (when (or package-selected-packages
            (yes-or-no-p
             (format-message
              "`package-selected-packages' is empty! Really remove ALL packages? ")))
    (let ((removable (package--removable-packages)))
      (if removable
          (when (y-or-n-p
                 (format "%s packages will be deleted:\n%s, proceed? "
                   (length removable)
                   (mapconcat #'symbol-name removable ", ")))
            (mapc (lambda (p)
                    (package-delete (cadr (assq p package-alist)) t))
                  removable))
        (message "Nothing to autoremove")))))
  • The patch in Bug#27822 should help (it will be included in Emacs 26.2). – npostavs Sep 5 '18 at 23:23
