So I don't know if there already is a good solution for this, if it is then I'm sorry. The possible solution that I saw on this site wasn't working for me and this one did.
I stumbled across a good solution that may help some of you guys. It did for me atleast and i thought I would share it with you all since it is a annoying error to get.
I'll make a step by step guide it's really simple.
1: If you have Tsprotector+, remove it and try to install the .deb file again. If it's still not working than continue with this progress.
2: Install Ifunbox and connect your Iphone to the computer.
3: Open Ifunbox and on the left sidebar you will see "Raw File System" Click on it
4: Change the file name /.cydia_no_stash TO /.cydia_no_stash-
5: Once you've changed the file name, disconnect you Iphone from the computer and open Cydia.
6: When you open Cydia it should start preparing file system. Let it finish.
7: Once done install the .deb file again and it should work.
Hope I helped you guys with this.
