Change file structure ownership to root recursively.
sudo chown -R root:root /opt/RubyMine

1. sudo /opt/RubyMine/bin/rubymine.sh
2. If applicable Import Settings | Enter License Key
3. Accept Terms

Launcher File -If Rubymine was launched prior to renaming the directory, then you may need to tweak the Unity desktop config file.
sudo vim /usr/share/applications/jetbrains-rubymine.desktop

4. LAMP(Linux + Apache + MySQL + PHP)
sudo apt-get install lamp-server^

It will be the root user password and you have to use that passord when connect mysql via any MySQL client or console.

You can install phpmyadmin as a client by runing the command below.
sudo apt-get install phpmyadmin

8. Install sublime text
Download sublime text .deb file from here http://www.sublimetext.com/
Then navigate the path where it's downloaded also make sure the dowloaded package is in a write permission directory.
Simple move it into /home path or any other directory under /home direcotry then run the command below

sudo dpkg -i package-name
sudo apt-get -f install

sudo apt-get install nano
sudo apt-get install vim

Go to software center and search by 'skype' then install

13. Install GIT or SVN as source code manager

14. RVM installation
You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh
open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm
if there was output, try to open new terminal, if it does not help then restart your computer.

Install RVM(this will install RVM and Latest ruby version):

\curl -L https://get.rvm.io | bash -s stable --ruby --autolibs=enable --auto-dotfiles
If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanatio
