Hi,
Stop trying to update kobo touch by this way.
Just download the update you need on the page linked below :

Extract the files in the zip files and copy them on the kobo in directory called ".kobo"
Unplug the reader, reload it and it will install the firmware.
2.0.2 works correctly on my device.
