Bug#1104178: elpa-doom-themes: upgrade fails: cannot overwrite non-directory ... with directory

[itd <itd@net.in.tum.de>]

Package: elpa-doom-themes
Version: 2.3.0-3
Severity: normal

Dear Maintainer,

I've tried to upgrade from bookworm to trixie [0] with:

| apt upgrade --without-new-pkgs

This command failed, producing (among others) the following output:

| Install emacsen-common for emacs^M
| emacsen-common: Handling install of emacsen flavor emacs^M
| Install elpa-doom-themes for emacs^M
| install/doom-themes-2.3.0: Handling install of emacsen flavor emacs^M
| install/doom-themes-2.3.0: byte-compiling for emacs^M
| cp: cannot overwrite non-directory './extensions' with directory '/usr/share/emacs/site-lisp/elpa-src/doom-themes-2.3.0/extensions'^M
| cp: cannot overwrite non-directory './themes' with directory '/usr/share/emacs/site-lisp/elpa-src/doom-themes-2.3.0/themes'^M
| ERROR: install script from elpa-doom-themes package failed^M
| ^[[1mdpkg:^[[0m error processing package elpa-doom-themes (--configure):^M
|  installed elpa-doom-themes package post-installation script subprocess returned error exit status 2^M

(To proceed with the upgrade, I've appended `elpa-doom-themes-` to the
failed command to remove the package for the time being.  With this
added, the minimal system upgrade succeeded.)
