New to this and trying to install algorand node on my spare raspberry pi 4b on Ubuntu Desktop 21.10. I followed the instructions on the algorand developer portal (i can only put 2 links).
sudo apt-get update
sudo apt-get install -y gnupg2 curl software-properties-common
curl -O [https://releases.algorand.com/key.pub](https://releases.algorand.com/key.pub)
sudo apt-key add key.pub
sudo add-apt-repository “deb [arch=amd64] [https://releases.algorand.com/deb/](https://releases.algorand.com/deb/) stable main”
sudo apt-get update
But when I type or copy the:
sudo apt-get install -y algorand-devtools
sudo apt-get install -y algorand-devtools
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
E: Unable to locate package algorand-devtools
any ideas?
thanks.

For raspberry Pi, you need to follow those instructions:
> **[Install a node - Algorand Developer Portal](https://developer.algorand.org/docs/run-a-node/setup/install/#installing-on-linux)**
The instructions you followed are for `arch=amd64`, which Raspberry is ARM.
