Upload tool 'avrdude' not installed

I installed avrdude on my Arch Linux but idk why it can not recognize avrdude.
How can I fix it?

Hi @mrhieu059 ,
arduino-cli doesn't use system-wide tools but needs its own tools in proper locations (eg. ~/.arduino15`). To make them available you should install the package for avr boards first.

Said that, supporting system-wide tools could be viable with some small changes, if someone is willing to take a look it would be cool 🙂

Hi @facchinm
Can you give me some idea how to install that package?
I am using Arduino Mega2560 R3

arduino-cli core install arduino:avr should make it 🙂

Thank you so so much, before I installed the core of avr but exactly is megaavr.
After I installed core of megaavr it worked now.
