Hi Domenico,
I suspect that you may have an old standalone org-mode installed.
Can you please send me the output of these commands:
dpkg -S ox.el
dpkg -l elpa-org
Also if you have installed org-mode via elpa/melpa that may also
be relevant.
find ~/.emacs.d -name 'ox.el*'
might be a clue if you have that.
It is possible that I would need to add a versioned conflicts to
the control file for the backport, so that it conflicts with an
old version of org-mode, if indeed that's what's going on. I
wouldn't be surprised to find other Emacs things packaged for
buster that are incompatible with Emacs 27.1, and probably much
older than the versions included with Emacs 27. I don't intend to
backport all of those things, especially since it is easy enough
to install newer versions from within Emacs, but I could add
Conflicts as appropriate.
I guess I would say my general advice, if you're going to use the
Emacs backport, is to purge *all* the emacs addons from buster
before you do.
Emacs does come with org-mode itself, and the org-mode contained
within Emacs 27 is several versions newer than the one in buster's
elpa-org package.
I didn't have a problem installing it on my systems, but then I
didn't have elpa-org installed.
For other DDs, a question...
I did find that the Emacs daemon mode (not the most commonly used
but it is used by a distinct minority of Emacs people) is broken
by a .el file contained in buster's dictionaries-common. I
therefore backported dictionaries-common from testing as well,
since that package gets installed as a dependency of a number of
other packages on the system. I am unsure if adding a versioned
conflicts to the Emacs 27 backport is the right thing to do here,
or if "apt-get -t buster-backports install emacs" will also
realize that it needs to upgrade to the backported
dictionaries-common in that case (I *hope* so?)
