If you get an error “no such device” at clean install:
error: no such device:
Failed to boot default entries.
At boot hold down the shift key, you will get the Grub menu.
In the grub menu press “e” to switch in edit mode.
Remove whole line starting with “search –nofloppy …”
Then Ctrl+X to boot.
Now system must start.
Then edit /usr/lib/grub/grub-mkconfig_lib file.
Find this finction:
prepare_grub_to_access_device ()
Comment this lines with “#” or remove it:
if fs_uuid="`${grub_probe} --device ${device} --target=fs_uuid 2> /dev/null`" ; then
echo "search --no-floppy --fs-uuid --set ${fs_uuid}"
fi
Save the file and run: “sudo update-grub” and restart. This works by me fine.
LogServer is python script to receive log messages from D-Link routers. 
I’m currently leaning toward Python and began doing so last week.
