Thanks Spearhead,
I am finely in step 6/6.
As I am working with an SSD I do want to put my dbases on my internal hard disk and not on the SSD.
My Ubuntu drive is SDA3 and the hard drive is SDC1.
In 6/5 I have entered sdc1/media/Opslag/URD as my download directory.
I have also checked the permissions.
I now have a failure on: Download directory not fount or not writable.
Did I filled in the right path?
Thanks and have a nice Pasen

Rob
