It all started after installing xemacs21 on my Ubuntu machine. Here are some of the outputs probably needed for troubleshooting. Let me know if I should add more. After trying

sudo apt-get -f install

Looks like you have broken emacsen-common package, try to reinstall it:

apt-get install --reinstall emacsen-common

and then perform removing (with purge) all the xemacs21 packages before trying to install again.

Keep in mind it will remove all your config files so better make a backup before purging.

List the installation files under /var/lib/dpkg/info/

ls /var/lib/dpkg/info/ | grep xemacs21

then remove them (e,g; from the question :info/xemacs21-mule*):

sudo rm -rf /var/lib/dpkg/info/xemacs21-mule.postinst
sudo rm -rf /var/lib/dpkg/info/xemacs21-mule.list
sudo rm -rf /var/lib/dpkg/info/xemacs21-mule.md5sums
sudo rm -rf /var/lib/dpkg/info/xemacs21-mule.prerm
sudo rm -rf /var/lib/dpkg/info/xemacs21-mule.conffiles

update and try to remove the package:

sudo apt-get update 
sudo apt-get remove xemacs21
sudo dpkg --configure -a

If you get and error with dpkg back up your status or all the content of the dpkg directory:

sudo cp /var/lib/dpkg/status /var/lib/dpkg/status.back
sudo cp -arf /var/lib/dpkg /var/lib/dpkg.backup

then restore the old dpkg profile :

sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo cp /var/lib/dpkg/available-old /var/lib/dpkg/available
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade
