Recently, I observed many issues with installation of edge-impulse-cli on ubuntu and raspbian on the forum This occurs usually due to administrator issues, npm errors, nodejs version or python version.
To sum it all up, I added a readme guide to follow it up here:

Edge Impulse CLI Installation guide
To install the cli on ubuntu 20.10 or raspbian os - follow this guide to avoid breaking your sudo command:
Option 1- Installation on Ubuntu 20.10:
$ curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
$ sudo apt-get install -y nodejs
Check if the version is v14 or above
$ node -v
$ curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh
The above script installs arduino cli
$ npm config get prefix
Type the above command and check if it returns usr back on your terminal.
if it does, you are good to go ahead! If it returns usr/local, head onto option 2. Make sure you have Python3.7 and above to execute all the functions.
$ sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
$ npm install -g edge-impulse-cli
This installs the Edge-impulse-cli and so, you can go ahead and execute the commands to configure mcu with the Edge impulse dashboard.
Bingo! Now you have installed the cli on Ubuntu 20.10
Option 2: Installation on Raspbian OS:
The installation on the Raspbian OS is a bit longer than ubuntu, because you need to change the installation path so that you do not require root/administrator permissions while execution of the CLI. Go ahead and follow the instructions for installation.
Instructions for manually changing default directory
To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use hidden directory in your home directory.
- Back up your computer.
- On the command line, in your home directory, create a directory for global installations:
$ curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
$ sudo apt-get install -y nodejs
Check if the version is v14 or above
$ node -v
$ curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh
The above script installs arduino cli
$ npm config get prefix
This command should return usr/local. Now follow the below steps, to set it on path so you do not require administrative permisiions
$ mkdir ~/.npm-global
Configure npm to use the new directory path:
$ npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
$ source ~/.profile
Now install the cli:
$ npm install -g edge-impulse-cli
This installs the Edge-impulse-cli and so, you can go ahead and execute the commands to configure mcu with the Edge impulse dashboard.
Bingo! Now you have installed the cli on Raspbian OS
Looks good! I added instructions to the docs: https://docs.edgeimpulse.com/docs/cli-installation
