I try to use suggested install script: `bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)` The commend returned: -sh: 8: Syntax error: "(" unexpected This is on a Debian Linux. Any ideas? ---

1 - what platform? 2 - what version of Debian? 3 - What user is running the command? 4 - does the user have SUDO ability? 5 - is anything else showing up when you run the script? 6 - Does it die right away or does it do some things first? ---

Also, if it does appear to get started then post the contents of `/var/log/nodered-install.log` **[Edit]** Another thought, is bash installed? It is available by default on most systems but maybe not yours. ---

If bash is not your current shell, try starting a bash shell and run the command from there. It looks as the error message comes from sh, not from bash. ---

> [@harelabb](#): > > If bash is not your current shell, try starting a bash shell and run the command from there. I don't think that should make any difference as the command explicitly invokes bash. As you say, the error suggests that it is from sh, which is why I wondered whether bash is not available. Until we hear from @mrohner we won't know. ---

> [@harelabb](#): > > It is the current shell that interprets the "\<" and parenthesis Oh yes, you are right, the script will not run when invoked from `sh` so your advice to run bash first and then the script is correct. Something new to learn every day, thanks. ---

with "sudo -i" I let run the command as root (although not recommendet) and it worked. Thanks for all your replies ---

No, definitely not recommended. Whether it worked or not depends on your definition of worked. Running node-red as root has risks. Did you try the suggestions above? ---

OK, did install an Ubuntu 20.04 from scratch, with all the updates a newer bash was installed. Your script now works flawlessly under a regular user with sudo capability. Thanks for your tips, ---
