Dear Keita, it's even simpler... I was using an instance of Emacs that started some time ago, when 12.1.x was still the best on Earth, and I updated all my packages w/o restarting Emacs (blushing emoticon). Since I restarted Emacs (I rebooted with a new kernel, that is) everything is fine again w/o fiddling with directories or configuration. Lesson learned, sorry for the noise on the mailing list, thank you. .g. ________________________________ From: Ikumi Keita Sent: Monday, January 13, 2020 15:46 To: Giacomo Boffi Cc: 39097@debbugs.gnu.org <39097@debbugs.gnu.org> Subject: Re: bug#39097: 12.2.0; Preview gets lost and doesn't find the LaTeX source file Hi Giacomo, >>>>> boffi writes: > in my .emacs I have > (setq package-archives > '(("gnu" .

I suspect that you have two instances of AUCTeX installation. In your previous message, I read ---------------------------------------------------------------------- current state: ============== [...] TeX-style-path '("~/.emacs.d/auctex" "/home/boffi/.emacs.d/elpa/auctex-12.1.2/style" "/home/boffi/.emacs.d/auctex/auto" "/home/boffi/.emacs.d/auctex/style" "auto" "style") ---------------------------------------------------------------------- which looks like that you have AUCTeX 12.1, while the "Subject" header begins with "...12.2.0" which suggests that you have 12.2. > In the hypotesis that I won't install the release tarball, what should I > do to install the latest auctex? Look into ~/.emacs.d/elpa/ and see what directories are there. If you have both auctex-12.1.2 and auctex-12.2.0, delete the former. And if you have customized `TeX-style-path', erase (or modify) the customization so that you can load from AUCTeX 12.2. Then restart emacs. Regards, Ikumi Keita
