package emacsen-common 1.4.22ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 5

I was just trying to install Filezilla from the ubuntu software center. Normally, when I try to install an app on xubuntu, the first time it will fail, and the second time it will succeed.
