problems with uploading programs to seeeduino


I am playing with the seeeduino LoraWAN wGPS-board. I have problems uploading a program to the board.

My environment:

PC: Ubuntu 18.04

Software: Arduino Ide 1.8.5

seeeduino: 06/07/18

Compiling a program within the Ide works, uploading the code to the board stops. Different messages appear, one of them is:
</s>No device found on ttyACM0 Set binary mode Beim Hochladen des Sketches ist ein Fehler aufgetreten Send auto-baud Set binary mode<e>

The board is connected to the PC via USB, Ubuntu creates it as /dev/ttyACM0. Via the ls-command I can check this, dmesg also reports this:
</s>[ 7693.740790] usb 1-4: new full-speed USB device number 20 using xhci_hcd [ 7694.056674] usb 1-4: New USB device found, idVendor=2886, idProduct=000c [ 7694.056678] usb 1-4: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 7694.059463] cdc_acm 1-4:1.0: ttyACM0: USB ACM device <e>

</s>august@August-Ryzen:~$ ls -l /dev/ttyA* crw-rw---- 1 root dialout 166, 0 Okt 26 11:07 /dev/ttyACM0 august@August-Ryzen:~$ <e>

Can you pleas give me an advice.
