Dear Jose, Hello again! When I install sawfish on Trixie, I get: Setting up sawfish (1:1.11.90-1.2+b1) ... update-alternatives: using /usr/bin/sawfish to provide /usr/bin/x-window-manager (x-window-manager) in auto mode ERROR: sawfish is broken - called emacs-package-install as a new-style add-on, but has no compat file. Install sawfish for emacs ... but it seems to be happily installed. I see similar when removing the package. I see similar on another machine running Buster, where I'm doing the reportbug dance. In 2019, I saw similar on Stretch. I think it's reproducible and old. It'd be nice if it didn't SHOUT something that looks important but perhaps isn't. No biggie but thought I should mention it, having failed to find any solution on the interwebs. https://piuparts.debian.org/trixie/needs_rebuild_issue.html ... looked like it might be relevant but I didn't understand.
