Hello @OrhanYigitDurmaz,
thanks for the contribution, it is appreciated!

Adding more instructions is always welcome. In this case, we believe that instead of adding instructions for different Linux distros directly to the error message, we should go the opposite way - simplify the message and extend the Troubleshooting guide section in the docs instead. Would you be interested to move the information there?

Also, please take a look at the github-actions bot recommendations above this comment. The commit message is missing the type and scope.

Thanks!

You're right. Then giving the link to here is better. Maybe you could also add this to the troubleshooting section?

Also looks like lint_esptool has some broken dependencies and thus, fails.

Do you want to finish the PR, or should we take over, then?

That's unrelated to this PR, don't worry about the failure.
