How to uninstall broken jedit on ubuntu?

You can resolve in this way:

# cd /var/lib/apt/lists

remove the file(s) dl.sourceforge.net_sourceforge_jedit_._Packages and dl.sourceforge.net_sourceforge_jedit_._Sources

# rm -fr dl.sourceforge.net_sourceforge_jedit_._*

then

# cd /var/lib/aptitude

open the file pkgstates and delete any related lines to the packages jedit

finally

# cd /var/lib/dpkg

open the file status and lete any related lines to the packages jedit


# sudo apt-get clean
# sudo apt-get update

Now I'm able to use apt-get or synaptic to install/remove/update packages !!!
