avrdude done.  Thank you.

Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

Have you done this
sudo usermod -a -G dialout yourusername

3

sudo dmesg -w
gives the following output when the usb cable is removed and inserted .

Note: I must use sudo and a password.

No , what does this line do?

5

Sounds like your user is not a member of the dialout group. What's the result of running the groups command?

6

This is what I get.

db@db-VivoBook-15-ASUS-Laptop-X540MA-X540MA:~$ groups
db adm cdrom sudo dip plugdev users lpadmin
7

It fixes your problem

8

And you're not in the dialout group. That's almost certainly the problem then, and @sonofcy has the solution. You can double check that dialout is the correct group by doing ls -l /dev/ttyUSB0 and checking which group it belongs to.

9

I have no idea what this means.

db@db-VivoBook-15-ASUS-Laptop-X540MA-X540MA:~$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Sep 12 20:50 /dev/ttyUSB0

Ok , thanks.
I did type in those lines but there was reply or any new message so I dont know if it worked.

Access is still denied.

11

If you don't know a basic ls command, why are you using Linux?

12

There is another group I have seen, but I don't know what it is or where to find the information.

13

Did you reboot?

14

How did you learn to drive?

No , but I will try it now.

15

You don't have to reboot; simple logout and login is sufficient.

16

@mikedb is up to a new challenge.

:rofl:

17

I read the driving manual our government provides. For Linux I read several books.

18

The instructions I read said reboot.

19

You read the wrong books :wink:

20

Thanks that worked.The Serial monitor is also working.

I rebooted before @sterretje suggestion to Log out.

So the very first time you sat behind a steering wheel you pass the test.
