Synaptic package manager warning

[mike00]

I recently installed Knoppix 7.0.5 and went to reload packages in Synaptic Package Manager and a long list of packages were downloaded and when I clicked Mark All Upgrades I get a warning that reads Some Packages Cannot Be Verified. What should I do?

You cannot upgrade Knoppix! It is a Live System, not a distribution like for example Debian.

If you really need new versions of some packages, you can try to upgrade step by step and you have to know, how to handle the problems with violated dependicies.
