Hi,

I'm getting the following error, both with 'emacs' or 'emacs -q -no-site-file':

I've just tried it here with the same results. 

The problem is in the defconst form
'apt-utils-completing-read-hashtable-p' in the file apt-utils.el where a
test is made for the version of Emacs being used, and whether
completing-read supports hash table as input.

A quick fix would be to change the test as indicated:

(defconst apt-utils-completing-read-hashtable-p
  (and (not apt-utils-xemacs-p)
       (or
        ;; Next released version after 21.3 will support this
        (and
         (>= emacs-major-version 21)
         (>= emacs-minor-version 5))           ; <----- was 4
        (>= emacs-major-version 22)
        ;; As will the current pretest
        (string-match "\\..*\\..*\\." emacs-version)))
  "Non-nil if `completing-read' supports hash table as input.")

or simply to take out the major-version test < 22, on the likely
assumption that the next major release of Emacs will be version 22 (and
not 21.5).

Hope that helps.

Thanks Neil, I tried your first solution, and it took care of the problem,
but somehow font-locking was gone. I just checked the author's website,
and followed up to the package's latest version:

https://alioth.debian.org/projects/mph-emacs-pkgs

which has the following version of the defconst:

(defconst apt-utils-completing-read-hashtable-p
  ;; I think this is a valid way to check this feature...
  (condition-case nil
      (or (all-completions "" (make-hash-table)) t)
    (error nil))
  "Non-nil if `completing-read' supports hash table as input.")


This seems to be working normally again.

Cheers,
