I am using an Arduino Uno. I am using Linux Mint 18 and the stock Arduino IDE from the Repo. It is version 1.0.5. I did a complete update of everything on my machine using the command: apt update and apt dist-upgrade. That brought down all updates and the latest Kernel. My kernel version is 4.4.0-53.74.
With that update, I can no longer upload to my arduino. The error it gives me is: "processing.app.SerialNotFoundException: Serial port '/dev/ttyACM0' not found. Did you select the right one from the Tools > Serial Port menu? at processing.app.Serial.(Serial.java:191) at processing.app.Serial.(Serial.java:77) at processing.app.debug.Uploader.flushSerialBuffer(Uploader.java:77) at processing.app.debug.AvrdudeUploader.uploadViaBootloader(AvrdudeUploader.java:175) at processing.app.debug.AvrdudeUploader.uploadUsingPreferences(AvrdudeUploader.java:67) at processing.app.Sketch.upload(Sketch.java:1671) at processing.app.Sketch.exportApplet(Sketch.java:1627) at processing.app.Sketch.exportApplet(Sketch.java:1599) at processing.app.Editor$DefaultExportHandler.run(Editor.java:2380) at java.lang.Thread.run(Thread.java:745)"
The Port selection is "Greyed" out also, so I am not able to select a port at all.
I don't know what to do. I did a search for this issue on this forum but didn't find anything remotely close to it. I think I put all the info down here, but if you need further info please drop me an email and I will furnish it for you. Thank you. @kd7sjt
