Running Problem

[GraceAredel]

Which operating system are you using:
Ubuntu 16.04 LTS 64bit

Please describe the steps you took when trying to install Yarn and what went wrong:
I installed Yarn firstly as usual by an official instruction and everything was well. Then I installed jest, wrote a first test, run yarn jest and got an error error Command "jest" not found.
If i got it right, there are a solution for this error so I decided to try to install a Nightly version which is 1.16.0-20190324.1147 by also an official instruction:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://nightly.yarnpkg.com/debian/ nightly main" | sudo tee /etc/apt/sources.list.d/yarn.list

So the expected result was to get this 1.16 version of yarn
And the actual result:
`root@ubuntu:/usr/share/yarn# yarn --version

1.13.0-20181121.1436`

@GraceAredel after you have added to the list of repositories, you need to upgrade the software.

Usually this is done by command like

apt-get update
apt-get upgrade

Please add pointers to the specific instructions you where following, so they can potentially be improved.
