What is the current behavior?

Every invocation produces error message:

yarn --version
/usr/share/yarn/lib/cli.js:46099
  let {
      ^

SyntaxError: Unexpected token {

If the current behavior is a bug, please provide the steps to reproduce.

Installation is per docs. Here's some history:

 1301  apt-cache policy yarn
 1302  curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
 1303  sudo systemctl restart nut-server nut-client
 1304  sudo systemctl status nut-server nut-client
 1305  grafana-cli plugins install grafana-image-renderer
 1306  uname -a
 1307  sudo apt update
 1308  apt-cache policy yarn
 1309  sudo nano /etc/apt/sources.list/
 1310  ls /etc/apt/sources.list
 1311  ls /etc/apt/sources.list/
 1312  sudo nano /etc/apt/sources.list
 1313  echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
 1314  sudo apt update
 1315  apt-cache policy yarn
 1316  sudo apt install yarn
 1317  apt list --upgradable 
 1318  sudo apt update
 1319  sudo apt upgrade

And output I was able to copy-paste:

What is the expected behavior?

Expected yarn to run without error.

Please mention your node.js, yarn and operating system version.

Seems this has been hiding for a while - the most recent working package for my platform is 1.12.3-1. Note I'm not impacted by cmdtest:

lar@rpi-lgr13-0199:~/grafana-image-renderer$ apt policy cmdtest

I used apt purge and autoremove to progressively step backwards... Here's v1.19.0-1:

Is this still an issue on v1.21.1? If so, please comment. Closing for now

It stems from Node (of course). I updated nvm to use a recent node version and yarn is fine.

I have to use Yarn on a project that uses Node 5.12.0. It would be nice to see this bug fixed so that Yarn can continue to support Node 5.
