Cannot install avr platform

Development Tools IDE 2.x
1

Hello! I have just installed the Arduino IDE 2.0.3 but am not able to get it working.
when trying to verify/upload, I first get the error message:

 `Compilation error: Platform 'arduino:avr' not found: platform not installed

Then when trying to install Arduino mega AVR boards by Arduino, i get the error:

   Downloading packages
   arduino:avr-gcc@7.3.0-atmel3.6.1-arduino5
   arduino:avrdude@6.3.0-arduino17
   Failed to install platform: arduino:megaavr.
   Error: 13 INTERNAL: Server responded with: 503 Service Unavailable

When trying to install Arduino AVR boards by Arduino, i get the error:

   Downloading packages
   arduino:avr-gcc@7.3.0-atmel3.6.1-arduino5
   arduino:avrdude@6.3.0-arduino17
   Failed to install platform: arduino:avr.
   Error: 2 UNKNOWN: read tcp 10.229.84.22:62516->104.18.13.241:80: wsarecv: An existing 
   connection was forcibly closed by the remote host.

I have tried this over the course of 2 days and it still isnt working. What is there I can do to remedy this? Thank you!

Your topic has been moved to the dedicated IDE 2.0 section of the forum.

Hi @alojandro. It is possible your firewall or other network security system (e.g., proxy, VPN) might be interfering with Arduino IDE's ability to download these tools from the Internet. Are you aware of any special network security systems you (or the systems administrators if you are in an institutional setting such as a workplace or school) have in place that might be doing this?
