Setup Ubuntu 14.04 Trusty Tahr Discussion

I am new so please don't be harsh. I want to learn Ruby on Rails and I was told that I should install it on Ubuntu so I downloaded Ubunto 14.04 LTS (the desktop version). That is great! Now I wanted to install Ruby on Rails. I did a search and found your website. I am afraid I am lost at: The first step is to install some dependencies for Ruby. Where do I enter command lines? I can't even find help on Ubunto LOL. I am a Windows vet and trying to convert but for now I am lost for a monent and would appreciate your help. Thanks so much.
No worries! There is a application called Terminal that you want to type these commands in. Open up that and type them in there and you should be fine.
Thank you. The terminal app worked perfectly. Just a note that with Ubuntu 14.04 I was getting an error message stating they could not verify the authenticity of the host github.com after creating my key but gave me the option to add it permanently. When I ran the command line to verify my key I got the message
Warning: Permanently added the RSA host key for IP address '192.30.252.130' to the list of known hosts.
Hi Msjay2u! You've successfully authenticated, but GitHub does not provide shell access.
The next time I ran it to verify I just got the success message without the warning line.
Seems there is a problem with their DNSSEC (Domain Name System Security Extensions)
That error/warning is just to make sure you know you're connecting to a computer that you've never talked to before. Glad everything is working well!

Instead of
sudo sh -c "echo 'deb http://apt.postgresql.org/p... precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
use
sudo add-apt-repository 'deb http://apt.postgresql.org/p... precise-pgdg main'

Great article thanks! I seem to be unable to install other versions of Ruby. For example, if I cd into a directory and try to install Ruby 2.0.0-p247 I get an error on compile. Is this due to the deadline issues going around? Anyone know how to fix this? I tried to install using the patch as noted above, but that did't work either.
You can run the following command if you'd like to install Ruby 2.0.0-p451 instead of 2.1.1:
curl -fsSL https://gist.github.com/LeonB/10503374/raw | rbenv install --patch 2.0.0-p451
It requires a different patch than 2.1.1 does.

why not use PostgreSQL 9.3 from the Trusty Thar repo?
You're right, I'll switch it over to the Trusty repo. Eventually when PostgreSQL's official repo is available for trusty I'll switch it back because you're always guaranteed to get the latest version on their repo. The Ubuntu repositories tend to lag behind the official releases so I lean towards using the postgres provided ones if I can.

Installing from source can cause frustration down the road when you need to work on a project written with a different ruby version. Usually the changes needed to get it working on a different ruby version are minimal, but working with other people who have conflicting ruby versions becomes difficult if you're back- or forward-porting code. But on a production environment, or a box that will only be used for personal ruby projects, it's sometimes nice to know that your ruby is installed in the simplest way possible - directly in the path.
How about adding a few steps to setup an app server like unicorn passenger or puma? That would be great
Good idea, but those are more for production environments. The Deploy Rails tutorial is more geared for setting up a server and covers Nginx + Passenger. This tutorial is for your development environment.

Please mention common compile fail because of "readline error" and this patch that fixes it https://github.com/sstephen...
This is fixed now in the latest versions of 2.1 and 2.0 that were released yesterday!

HI i got this error while installing ruby with rvm on 14.04
Partial file(18). Only a part of the file was transferred. Removing partial and re-trying.
rvm installed successfully.
rvm requirements is passed
Sounds like the download got interrupted. You probably should delete the file they mention (assuming they tell you which one didn't finish) and try again.

Thanks! Went well. One suggestion, SQLite!
You should have sqlite3 installed if you followed all the steps. And to generate a Rails app with Sqlite, just skip the -d option and use rails new myapp
I'll add a comment to the last part to make that more clear. Thanks!

Hi for `add-apt-repository` command I think what you need is "software-properties-common" package instead of the python stuff, see: https://askubuntu.com/quest...
Hi Chris,
Great article. I was able to follow the steps untill MySQL installation, after that I created an app,
$rails new myapp -d mysql
And was shown the following error,
Fetching gem metadata from https://rubygems.org/...........
Fetching additional metadata from https://rubygems.org/..
Resolving dependencies...
Gem::RemoteFetcher::UnknownHostError: no such name (https://rubygems.org/gems/r...
An error occurred while installing rake (10.3.2), and Bundler cannot continue.
Make sure that `gem install rake -v '10.3.2'` succeeds before bundling.
run bundle exec spring binstub --all
bundler: command not found: spring
Install missing gem executables with `bundle install`
Please help me out. I did a "bundle install" but it just said "Unknown Host name"
Sounds like you had internet connectivity problems. Try running it again and see if it works next time?

Hello,
I am new to Rails: How can update my config/database.yml file to match the database username and password.
You can just open that file in your favorite text editor and set the username and password keys inside it. I'd recommend using Sublime Text or something similar to do that.
