After uninstalling xemacs-packages-sumo and installing xemacs-packages-all instead advice.el is no longer available on the system. It would be great if a package containing this could be added. Reproducible: Always Steps to Reproduce:
advice.el is provided by the xemacs-base package, which should be installed as part of xemacs-packages-all. Could you check the following? locate advice.el (just to be sure that the file isn't installed) whether xemacs-base is installed according to your package manager if advice.el is amongst the files installed by xemacs-base (equery files xemacs-base)
advice.el was not present anywhere on my system (locate advice.el did not report anything) but xemacs-base was reported as installed. Reinstalling xemacs-base fixed all my problems though. So thanks a lot!
