I installed Arduino IDE 2.0.0-rc2-nightly.20211218 on my openSUSE Linux Leap 15.3 box today, and tried an OTA upload to ESP8266 Lolin Wemos D1 R2. I selected the board, then selected the port address.(I have 4 of these on my local network, and all four were listed). After the successful compile, I got this error --
Usage: espota.py [options]
espota.py: error: option -p: invalid integer value: '{upload.port.properties.port}'
Upload error: Failed uploading: uploading error: exit status 2
It appears that passing the IP address to the -p option has a problem.
This board was close by so I connected it to a USB port, re-configured the parameters, and it uploaded OK.
I was using IDE 1.18.13 to perform OTA uploads with no problem.
