I find the problem :
When a created a virtual disk for my virtual machin i put an automatic allocation and a maximal size to 8Gio instead of initial size to 8Gio.
So there is not enought place in the disk.
Now it works, thanks you a lot.
Maybie, after mksquashfs you should add this line :
- Code:
if test $? -eq 1
then
echo "An error occur see log file"
exit 1
fi
