I tryed to install Node-RED using script for Debian:

```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

```

but install failed.

```auto
Update Node.js LTS ✘ Failed to install Node.js - Exit.

```

OS: Ubuntu MATE 18.04 LTS  
Hardware: Raspberry Pi 3 Model B

I found following message in /var/log/nodered-install.log:

```auto
gpg: can't connect to the agent: IPC connect call failed

```

I tryed to install node.js 12.x before installing Node-RED.  
refs: [https://github.com/nodesource/distributions/blob/master/README.md](https://github.com/nodesource/distributions/blob/master/README.md)

```auto
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs

```

After installing node.js 12.x, I retried to install Node-RED using script for Debian:

```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

```

Install succeeded.

I think this is strange.  
Is there something to wrong in the install script for Debian?

the failure is down to the gpg error - presumably then not allowing it to install nodejs - This is not a common error (if you google it) - and seems to be to do with the underlying OS install - so not something we can really anticipate or handle.  
Installing manually as you did is the easy and best way round it I suspect.

I did not do anything special while installing OS...  
For now, I use this workaround.  
Thank you.
