Colin, when you see this: Is there any personal info in the install log that I should remove before posting it?
I donāt think so. Your user name will be there but unless you have changed it that is just pi.
HALLELUJA! The forum strikes again! āNew users canāt upload attachments.ā 
Are you by any chance on any working forum, like AVSForum, EventGhost, Promixis or something?
Edit: Or Home assistant. Same crappy software, but at least Iām not new thereā¦
Edit 2: Administrators, I applaud your work to create a new forum for Node-RED, my acidic comments are more about the one mistake you made, choosing this piece of you know what forum software to run it on.
@Mastiff Iām sorry that youāve been frustrated. By default the platform flags you as a new user for 24 hours after registration (I believe).
In this instance, Iāve flagged you as a regular user so you should be able to post freely now.
We also have our slack team available - https://nodered.org/slack - if youād prefer.
If you have any constructive feedback, then please do share it in #meta. Simply complaining about our choice isnāt going to get very far.
Well, it got me this far, didnāt it! 
Colin, hereās the log!
Oh, and no, I donāt prefer slack. I prefer good, old-fashioned forum software that is more about the content then cool ābadgesā and āHow about a picture for your accountā. But then Iām oldā¦
Edit: No, it didnāt get me this far. Still the ānew users canāt upload.ā
Mastiff, if it helps & is quicker, zip it, mail it to me and I will upload

Thanks, Walter! Done. 
Installasjonslogg Node-RED.txt (66.4 KB)
Sorry, Walter. I forgot to zip it. But as you have probably seen in the years youāve known me I have a big problem zipping it! 
What do you see on the console when it gets as far as it gets?
I only see what I showed in the other thread. It says that Update Node.js LTS ā Failed to install Node.js - Exit and then it goes to command prompt.
Are you running the bash <(curl... command from https://nodered.org/docs/hardware/raspberrypi ? If not then try that.
If that still fails then what do you see for
node -v
npm -v
If npm -v says it is not installed then
sudo apt-get install npm
and try the upgrade script again.

I tried the curl command now, it gave the same result as the shorter command.
As for the versions:
pi@raspberrypi:~ $ node -v
v4.2.1
pi@raspberrypi:~ $ npm -v
ERROR: npm is known not to run on Node.js v4.2.1
Node.js 4 is supported but the specific version you're running has
a bug known to break npm. Please update to at least 4.7.0 to use this
version of npm. You can find the latest release of Node.js at https://nodejs.org/

That was written yesterday, not so long after your previous answer, Colin. But of course I was forbidden from posting it:
Knolleary, I donāt know what you have done, but you have not made me a regular user, because I was blocked from writing more than 15 posts in a day. Not when clicking āreplyā, but AFTER I had spent time writing theanswer! Another stellar example on the fantastic skills of the code monkeys behind this software! I hope I can post now. But Iām not blaming you for that, of course! My guess is that the administration of the forum software is as confusing and ācoolā as the user experience.
Edit: Nope, still 10 minutes leftā¦
Unless you have lots but of other things on the sdcard, why not start again with a fresh download of Raspbian.
Mainly because I spent months getting Node-RED and Home Assistant (for ZWave, because I never got Node-RED reliable with my door lock) to play nice and work as they should. But yeah, that will be my final option, if this attempt fails. I have notes and forum posts that will help me, so I guess this time it will probably only take a full weekendās workā¦ 
Edit: The reason it took so long (with lots of patience and help from Krambriw) was mainly because Iām a Windows guy, and I wanted everything to be exactly the way I wanted it. (Yeah, thatās meā¦) Iām sure you guys would have done it in an evening.
I think I have an idea what may be going on, I think there is a flaw in the install script under some unusual circumstances. Try this. Some of these commands may say not installed or not found but donāt worry.
sudo apt-get remove nodejs npm
sudo apt-get autoremove
sudo rm /usr/bin/node
sudo rm /usr/bin/npm
Save the result of those in case I ask to see it later.
Then run the bash <(curl command again.

And the end result was the same, the curl script broke on update node.js.
Edit: Oh, flaws under unusual circumstances... I think I'm a magnet for those!
Ok, in fact I have managed to get a pi into the same state as yours. Just investigatingā¦
