I installed on HD Sparky Linux 3.6 Razor-Qt i586.
All works fine.
I can install/upgrade packages with apt-get or synaptic but when i launch "System Upgrade" I receive this error message:
It's Live System!
Install Sparky on a hard drive then upgrade it.
I have a multi OS system with several linux distro.
During Sparky installation I choose to install grub on the first sector of root partition.
After reboot, in another linux OS, I copied the Sparky /boot/grub/grub.cfg menuentries on my personal 40_custom and I updated grub on MBR.
may depend on it?
I think not, but...
