Installation instructions for Fedora

Install the latest Arduino IDE from arduino.cc. $ sudo dnf -y install arduino will most likely install an older release.

Open Terminal and execute the following command (copy->paste and hit enter):

sudo usermod -a -G dialout $USER && \
sudo dnf install git python3-pip python3-pyserial && \
mkdir -p ~/Arduino/hardware/espressif && \
cd ~/Arduino/hardware/espressif && \
git clone https://github.com/espressif/arduino-esp32.git esp32 && \
cd esp32 && \
git submodule update --init --recursive && \
cd tools && \
python get.py

Restart Arduino IDE
