Replace Github-linguist with source github version

First of all, we need to locate our github-linguist files which will be replaced. We will also need ruby-build and gcc.

find / -name languages.yml
apt-get install ruby-build gcc
ruby-build 2.1.0 /opt/gitlab/embedded/service/gem/ruby/2.1.0
cd /opt/gitlab/embedded/service/gem/ruby/2.1.0/gems/
tar -xvzf v4.7.5.tar.gz
mv linguist-4.7.5/ github-linguist-4.7.5
rm -f v4.7.5.tar.gz
# Install all ruby dependencies
bundle install

Generate samples.json:

After download from github,

bundle exec rake check_samples

Otherwise, we will face this error in logs

2016-03-30_07:49:38.08294 No such file or directory @ rb_sysopen - /opt/gitlab/embedded/service/gem/ruby/2.1.0/gems/github-linguist-4.7.5/lib/linguist/samples.json

Fetch all ace modes

bundle exec rake fetch_ace_modes

Problems with bundle install
