I had to remove the emacs24 package, which led to the removal of several other packages (e.g. apel, org-mode, auctex, emacs-goodies-el), then reinstalled emacs24. This went well. Next I reinstalled the packages that depended on emacs24 (apel, org-mode, etc.). The install was succesful, but I notced this error message for each of them:
ERROR: org-mode is broken - called emacs-package-install as a new-style add-on, but has no compat file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1309414 Title: package emacs24 24.3+1-2ubuntu1 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/emacs24/+bug/1309414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
