Instaling , removing from synaptic , can not work, but from root terminal apt-get working, like:
apt-get install smart
You can use smart package manager , I hope this help, because I 'm not sure ... this package is corect .
And please , try make copy system with this bug ,
I can' not, my zen-linux not working,
last time I use pclinux from hard drive for resize partition and my partition lost, repairs will take too much time.
You can copy all system, make .iso file like pc-linux , or .img copy partition.
You can put copy pc-linux ( .iso file or .img , etc.) , example upload in dropbox server ( you have this app. in synaptic too for this)
Then, maybe someone will see and find the answer, what is the problem
