I have troubles to connect to arduino UNO via Arduino IDE on Ubuntu Of course ports are greyed out, but I set it up manually. When I try to upload I get following information:
java.lang.NullPointerException thrown while loading
gnu.io.RXTXCommDriver processing.app.SerialNotFoundException: Serial
port '/dev/ttyACM0' not found. Did you select the right one from the
Tools > Serial Port menu?
Installed packages:
$ apt list --installed |grep arduino

I am member of dialout group:
$ cat /etc/group |grep marcin
uucp:x:10:marcin

dip:x:30:marcin,marcin
video:x:44:marcin
plugdev:x:46:marcin
marcin:x:1001:
Port /dev/ttyACM0 is the proper one:
$ ls -l /dev/ttyACM0
crw-rw---- 1 root dialout 166, 0 paź 12 20:54 /dev/ttyACM0

Computer has been restarted, USB cable was pluged in and out several times with IDE turned on and off, No more ideas on how to move forward. Any help will be appreciated. Thanks.
