UnknownPackageError: Could not find the package with 'espressif/toolchain-riscv32-esp @ 8.4.0+2021r2-patch3' requirements for your system 'linux_x86_64'

Hi everyone

I am completely new to Home Assistant, ESPHome and anything arduino,

I have an ESP32 ready to go for my first project. I thought it would be easier to use ESPHome. Unfortunately, since I am not currently accessing HA over HTTPS, I cannot upload directly to it via USB.

I have therefore tried downloading the code to manually upload in Arduino IDE (I presume). I get the error in the title.

HA has been deployed as an OVA template to ESXi. ESPHome has been installed from the GUI as an addon.

Can anybody tell me how to proceed from here?
