An error in Cydia occured;
"The package com.memdefrag needs to be reinstalled, but I can't find an archive for it."

Cydia is stopped working now. Anyone familiar with this error?
I have been searching on google but it only gives me German websites, und mein Deutsch ist nicht so gut!

PROBLEM SOLVED.
Those facing the same problem, who have Mobile Terminal installed, typ the following;

su (and enter password, alpine by default)
dpkg --remove --force-remove-reinstreq com.memdefrag
dkpg --configure -a

This will do the trick. Don't make any typo's!

If you don't have Mobile Terminal installed, you can do the same through SHSH. Not sure if the commands are the same then...
