If you are trying to install
yarn dependency manager you might face this error that Ubuntu fails to install
yarn and goes on to suggest or install
Note, selecting 'cmdtest' instead of 'yarn'
This is because there is a different
yarn that is part on
cmdtest package and is older than the
yarn you are trying to install.
Solving this very simple. Instead of installing via
apt-get install it via npm
sudo npm install -g yarn
You can now check the version of
yarn with this command
