so the iso you remastered says that error, not a installed to hdd system?
you can remaster it without installing it anywhere using this script(s)
you gotta edit scripts for what desktop you want,etc
the script goes off of your /etc/apt so setup your sources.list
theres many variables to edit in the script so look at it carefully..
if you wanna remaster different iso edit that too
I've never seen that error so dont know?
are you using dist- or backup mode in remastersys?
