Hello!
I have installed Node-RED in a Raspberry Pi 3 using:
bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)
I have installed correctly, but when I go to Node-RED I can't install any package using Manage palette because it appears:
Failed to load node catalogue.
Check the browser console for more information
Thanks!
I've just done a fresh install this morning and am having the same issue.
RPi 3 - Raspbian Stretch Lite - node v8.15.1 - node-red v 0.20.4
Someone who already knows the answer may respond, but in the meantime, in a terminal run
node-red-stop
node-red-start
Then copy/paste the resulting log here, starting from the Welcome message. That may provide some clues.
Also do what it says in the error, check the browser console and see if anything useful there.
Can't see anything untoward but always welcome a second opinion...

BTW @mikel.garmendia sorry for hijacking your post but I think we're looking for the same answers here. Hope you don't mind. 
Hi!
It doesn't matter to me @mturbutt!
This is my result after node-red-stop + node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://169.254.0.22:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org

Browser console lists
https://catalogue.nodered.org/catalogue.json - "SyntaxError: JSON Parse error: Unexpected identifier \"object\""
Hi @ukmoose
I don't understand very well what I have to do.
How can I check the browser console?
Thanks!
Sorry - 0.20.4 broke something. 0.20.5 coming shortly.
It was more for @dceejay or @knolleary as it looked as if it is an issue in 20.4.
But to answer your question... its usually under the Developer/ Develop menu in your browser.
@knolleary Phew! I thought it was me. 
Been running node-red for 2 years and wanted a fresh install before setting my new house.
Where is the best place to check (or better still, get notified) of new releases please?
The get announced in the #news category.
Got it, thanks. Following that now.
0.20.5 now published with the fix. Sorry for the inconvenience.
That did it! Thanks a million.
@mikel.garmendia if you re-run in terminal:
$ bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)
You'll get the new release 0.20.5.
I've just tested it and it's working fine now. 
I have updated the Node-RED version it works fine!
Thank you very much @mturbutt and @knolleary
Hi,
Complete n00b here, I've ended up here as I'm following the Node-RED: basics to bots online course (https://courses.competencies.ibm.com/courses/course-v1:developerWorks+CB105EN+v1/info)
I'm too seeing the "Failed to load node catalog" message when using the Node-Red in the cloud. The console logs are as follows:
https://catalogue.nodered.org/catalogue.json SyntaxError: Unexpected token o in JSON at position 1
success @ red.min.js:16
j @ vendor.js:2
fireWith @ vendor.js:2
x @ vendor.js:5
b @ vendor.js:5
XMLHttpRequest.send (async)

j @ red.min.js:16
e @ red.min.js:16

o @ red.min.js:16
show @ red.min.js:16
n @ red.min.js:16
(anonymous) @ red.min.js:16
c @ red.min.js:16
(anonymous) @ red.min.js:16
dispatch @ vendor.js:4
r.handle @ vendor.js:4
I'm using Chrome...but seeing the same issue on any browser or machine that I'm using.
Is there something I'm doing wrong? Is it possible to add nodes to the palette if using the cloud version of Node-Red?
Any help gratefully received, thanks in advance...
This was a bug that was briefly introduced in 0.20.4 and fixed in 0.20.5.
