Arduino Port not working properly

Hi all,. What happened? - I successfully uploaded some code to the Arduino using the IDE (version 1.8) while following an Adafruit Arduino tutorial. 19); and. - I unplugged the USB lead to turn off the Arduino so I could rewire some components on the breadboard. - There was a problem when I attempted to upload the next sketch, and the port option in the Tools menu is now grayed out. - The Arduino board is in good condition; I can see it TX-ing in accordance with the loaded sketch. What have I attempted? - waiting 5 minutes or so; no change. - attempting a different USB port; no improvement. restarting - no improvement. no change after restarting and shutting down. - same as above but with laptop battery removed - nothing has changed. Though I'm sure I've encountered this problem before, I haven't been able to resolve it using Google. Since I only had to unplug the board, it must be a simple fix. We would appreciate any assistance.

Could be a few things. One guess would be that when you reconnected, the Arduino was assigned to a different device node. That could happen if there were still references to the original device node (like because the Arduino IDE still has a reference ?)

What are the output of ls -l /dev/tty[A,U]* before and after you connect your Arduino? This looks for device nodes for serial ports that map as ttyUSB or ttyACM.

Also, what are the output of uname -a and of pacman -Q linux (assuming you are using mainline kernel). Do the versions reported match?
