As mentioned in the earlier steps of the module "Quick Start: Visual Studio Code for Salesforce Development", I did the setup for Salesforce CLI on my ubuntu OS using Deb.
The setup was successful and I was able to see the version info with command 'sf --version'.
But as soon as I close the terminal and re-open to give command 'sf --version', the terminal will print 'command sf not found'.
So, I did keep the terminal open after doing the setup for CLI.
I followed the steps to create SFDX project and then authorize the org. As soon as I gave the playground alias name and enter, it shows following error.
Also, in the Output tab following error is always seen since the SFDX project is created. I have installed latest version of VS Code and Salesforce CLI. The Salesforce extension package was already installed.
If anyone has any solution or if someone faced similar issue while doing this challenge, please feel free to reach me out and let me know your thoughts.
Thank you for the answer. My computer has Ubuntu 20.04 OS. This time, I installed Salesforce CLI with NPM and now I am able to complete Hands-on challenges from the module as well.
