No, I purged it via terminal, and than used N9QTweak for install again bash from this one.. in the last post I didn't mean install/uninstall bash, but other apps.. for example, N9QTweak exited when I installed/uninstalled DEB Creator from Tweak X.. for one app isn't a big problem, remain only lock file to /var/lib/dpkg, but the problem starts when N9QTweak install/uninstall more application sequentially, because it exit before completing entirely the script, with a big problem to find what is left!! In fact to avoid this problem I choose to install/uninstall apps and sometimes also edit files (for this reason I read the source code ) only from terminal
