Crash on Login Attempt

? Offline

I decided to drop a NBB install on a DigitalOcean droplet for some testing on my lunch break following @psychobunny's guide. Despite not being able to connect to Chris Lea's PPA, I was able to get NodeJS and NPM up to date.
I was then able to do a quick configuration of NBB (without a database password - bad idea, I know - but let's look past that temporarily.)

The issue is that the board starts and runs, but throws an error and dies when I attempt to login. Given that it's pexpire, I'm going to assume it's related to password expiration.

Now - I can access and view my node install - but let's try logging in.

Alright, I saw something about the mentions plugin Let's try nixxing that temporarily.

Forum crashes again :cry: 
So, where to go from here?

@Albus Your Redis is out of date, upgrade to a version above 2.6.0.

 sudo apt-get install -y python-software-properties
 sudo add-apt-repository -y ppa:rwky/redis
 sudo apt-get update
 sudo apt-get install -y redis-server

psychobunny

I really should update my guide. For now I've left a note in the comments. Thanks

a_5mith

@psychobunny While you're at it, can you update the official docs to include sudo in the commands, just in case people have started following your guide and set up a new account that isn't root, then just copy pasted the lines in to Terminal. As even accounts with sudo privs need sudo adding for some reason. I think a few of the errors are caused by this point here:

apt-get update && apt-get dist-upgrade which asks are you root? Now the non observant would just change it to this sudo apt-get update && apt-get dist-upgrade which would still give the are you root error, but the error message may be missed by the user thinking apt-get update is working, the second command did too. Completely missing that you need sudo on the apt-get dist-upgrade.

It may be worth reworking the guide to work with 14.04 as that's pretty much latest and greatest. And I found that npm wasn't installed.

These seem to have fixed the issue, thanks for the assistance.

Just updated it, thanks The documentation is actually in the repository under /docs if you want to make any changes yourself, I'm not sure if everybody knows that

a_5mith

@psychobunny Now you mention it, I do. I'll have a look through, see if I can't contribute anything.

hey I just started and was following the guide for centOS
by default I had redis-server 2.4.
I'm trying to upgrade to a 2.6 + but having problem right now:
http://redis.io/topics/quickstart

If you know how to do it with yum would be nice to share, thanks!

edit: found here:
https://gist.github.com/nghuuphuoc/7801123
(only did step 1: install, not sure the other are needed or not)
