unable to upgrade from emacs 27 to emacs 28

unable to upgrade from emacs 27 to emacs 28

[John Covici]

Hi.  I tried to upgrade my emacs from 27 to 28, but I get lots of
errors in my .emacs file.

The errors seems to be around these lines:

(require 'package)
(add-to-list 'package-archives
		   '("melpa" . "http://melpa.org/packages/")
		   (when (< emacs-major-version 24)
			;; For important compatibility libraries like cl-lib
			  (add-to-list 'package-archives '("gnu" . "http://elpa.gnu.org/packages/"))))
(package-initialize)
(setq max-specpdl-size 22000)
(add-to-list 'load-path "~/.emacs.d/el-get/el-get")

(unless (require 'el-get nil 'noerror)
  (with-current-buffer

            type subtype)
        (while (not done)
          (setq type (cdr (assq 'type (get-text-property (point) 'mime-view-situation))))
          (setq subtype (cdr (assq 'subtype (get-text-property (point) 'mime-view-situation))))
          (if (and (eq type 'text)
                   (eq subtype 'html))
              (progn
                (setq done t)
                (mime-preview-play-curjrent-entity))
            (mime-preview-move-to-next)))))))


The first error was the use-package line.

Is there some further upgrade tasks I need to do to get this working?

Thanks in advance for any suggestions.

Should I report a bug against Gnus for now being able to guess the
errors you saw?

Not using gnus, using wanderlust for mail, gnus for news.

My suggestion is to post the errors ;-)

OK, here is the error message, did not seem to be that helpful .

What is this mime-play package?

Re: unable to upgrade from emacs 27 to emacs 28

[John Covici]

mime-play seems to be a part of the wanderlust mailer, so I will see
what they have to say.

That error message is telling you there is something in your init file
(or one of the files it loads) which Emacs is unable to parse correctly.
From the error message, it looks like the issue may be with the
mime-play package. I have no idea what this package does as it is not a
part of Emacs. Quite likely the package needs to be updated to work with
Emacs 28. 

Note that it could also be some other error in your init file which is
confusing the parser as it tries to read your init file. I would start
by commenting out the section relating to mime-play and see if Emacs is
then able to start. If it does, then you probably need to raise an issue
with the mime-play maintainers (or check there isn't an update for Emacs
28). 

If commetning out mime-play still fails to get Emacs to start, then the
error is likely somewhere else in your init file. In this case, you may
need to use the init file bisect technique - comment out the last half
of your init file and start Emacs. If it start, you know the issue in
the second half of your file, if it still doesn't start, you know it is
in the first half. 

Proceed with commenting and uncommenting bits of your init file until
you narrow down the problem to the specific point where the failure
occurs and then invesitgate the reason. 

It is also a good idea to read through the NEWS file for Emacs 28. Each
new version of Emacs adds new features and sometimes introduces
new or altered functionality which may require updating/changing your
init file. The NEWS file can help narrow down the search space when you
encounter problems.

Yes - how about actually including the error messages
so we have some clue?

Based on available information, my assessment is the upgrade failed
because your socks were the wrong colour. 


On a serious note, I would go through the NEWS and PROBLEMS files for
Emacs 28 to see if that gives some guidance. If the errors are
associated with the parts of your init you have posted, it would
indicate all are related to externally maintained packages which are not
part of Emacs. It could be these packages need to be updated to be
compatible with Emacs 28 or it could simply be that failures early
(especially around el-get) are causing installation of other external
packages to fail. Again, without knowing what the errors were, we have
no clue.

I thought I had fixed that problem back in Emacs-27.

Unfortunately, that patch only works with cotton based socks. Woolen
knitted sockes still fail. There may also be problems with some nylon
blends, but I have trouble repeating them consistently.

Possibly this is a manifestation of the
infamous "Emperor Has No Socks" problem.
