Computer Kubuntu 20.04
Installed Arduino IDE version (2:1.0.5+dfsg2-4.1). (latest?)
Starts up, but doesn't have a sidebar or the Boards Manager.
My task is to try and update my 3D printer Anet board to Marlin code. I am starting with Marlin 1.1x and will increase to latest version if I can get this working, but without being able to add the ANet board I can't do anything.
Hi @peterm7. Due to your use of APT to install the Arduino IDE, you got a version that was outdated by close to a decade, before the introduction of Boards Manager.
You can get the latest official Arduino IDE by downloading it from the "Software" page here:
No idea if it's the latest. I suspect that you installed via the package manager. That version used to be far (and I mean far) behind the official release. Missing the side bar indicates that the version is 1.8.x or older.
I suggest that you uninstall and download from https://www.arduino.cc/en/software. You have a choice of 1.8.19 or 2.0; the latter still has some minor issues but is very usable.
