I mistakenly interrupted a board package update in Arduino (through VNC on Raspberry Pi 2) and now I am having problems compiling a sketch to the board.
I attempted to uninstall arduino, then reinstall without success. I also attempted to reinstall gcc-avr and arduino-core.
Error message: Arduino: 1.8.5 (Linux), Board: "Arduino Nano, ATmega328P"
fork/exec /home/pi/.arduino15/packages/arduino/tools/avr-gcc/4.9.2-atmel3.5.4-arduino2/bin/avr-g++: no such file or directory Error compiling for board Arduino Nano.
Additionally, gcc-avr and arduino-core were both set to update manually?
Are there any suggestions on a correction?
