Preparations

You will need to make sure that your username is on the sudo authorized list located at '/etc/sudoers'.

If you're going through a proxy, add the following to the ~/.curlrc file:

proxy=host:port
proxy-user=username:password

NodeJS needs to be built from source on 10.04.

git clone git://github.com/ry/node.git
cd node
./configure
make
sudo make install

All Releases (no RVM)

For all Ubuntu releases run this if you are not going to use RVM:

wget http://ftp.us.debian.org/debian/pool/main/r/rubygems/rubygems_1.8.24-1_all.deb -O rubygems.deb && sudo dpkg -i rubygems.deb

Install RVM (optional but currently highly recommended)

You can install Ruby on a clean per user basis via RVM. This is currently recommended to get the latest Rubygems version. It is recommended that you install rvm from source since Ubuntu's version is lagging.

To install rvm from source, execute the following command:

curl -L get.rvm.io | bash -s stable --auto

Now read rvm requirements and ensure libyaml-dev is installed. Then install Ruby via RVM:

rvm install 1.9.3-p448
rvm use ruby-1.9.3-p448@global

Install Bundler

To install Bundler, run the following, if you aren't using RVM you need to do it as root (prepend it with sudo):

gem install bundler --no-ri --no-rdoc

To get bundle to work (bundle install step later), you might need to make a symbolic link if you aren't using RVM:

sudo ln -s /var/lib/gems/1.8/bin/bundle /usr/local/bin/bundle

Done!

Congrats! You have all your dependencies installed. Go back to Installing and Running Diaspora

Appendix

To install build tools, run the following (includes the gcc and xml parsing dependencies):

sudo apt-get install build-essential libxslt1.1 libxslt1-dev libxml2

Ruby

To install Ruby 1.8.7, run the following command:

sudo apt-get install ruby-full

Please note that you need to have Universe enabled in your /etc/apt/sources.list file to install ruby using apt-get.

MySQL

This installs MySQL, you also need the libmysqlclient-dev and libmysql-ruby packages.

sudo apt-get install mysql-server libmysqlclient-dev libmysql-ruby

To start MySQL run:

sudo service mysql start

sqlite

sudo apt-get install libsqlite3-dev

OpenSSL

You already have OpenSSL installed but you need the libssl-dev and libopenssl-ruby package too:

sudo apt-get install libssl-dev libopenssl-ruby

You need to install the dev headers. To install them, run the following:

sudo apt-get install libcurl4-openssl-dev

ImageMagick

To install ImageMagick, run the following:

sudo apt-get install imagemagick libmagick9-dev

If you're on Ubuntu 10.10 or 12.04 use the following instead:

Git

To install Git, run the following:

sudo apt-get install git-core

Redis

To install Redis, run the following:

and try the step again.
