Upgrading Ubuntu from 18.04 – 20.04 is easy and takes a few moments. When it comes to Ruby on Rails app development, you need the latest version of Ubuntu to achieve smooth performance.  <\/p>\n\n\n\n

The command for upgrade is shown below:<\/p>\n\n\n\n

sudo apt update && sudo apt upgrade<\/code><\/p>\n\n\n\n

After upgrading Ubuntu, some sets of binary libraries were found missing while bundling the dependencies and serving the rails application. <\/p>\n\n\n\n

You will also notice the following enlisted set of errors arising while serving the bundling the dependencies or serving the Rails application or if there are missing SSL certificates for a specific ruby version in the local machine:<\/p>\n\n\n\n

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.<\/code>
\nGYou must add \/C=BE\/O=GlobalSign nv-sa\/OU=Root CA\/CN=GlobalSign Root<\/code>
\nCA to your local trusted store<\/code><\/p>\n\n\n\n

OR<\/p>\n\n\n\n

An error occurred while installing nokogiri (Nokogiri Version),<\/code>
\nand Bundler cannot continue.<\/code><\/p>\n\n\n\n

OR<\/p>\n\n\n\n

-bash: cd: \/usr\/share\/rvm\/usr\/ssl: No such file or directory<\/code><\/p>\n\n\n\n

OR<\/p>\n\n\n\n

SSL_connect returned=1 errno=0 state=error: certificate verify failed<\/code><\/p>\n\n\n\n

If you are facing any issues related to the specific nokogiri version used for existing Ruby on Rails rapid application development or SSL\/CA certificates. <\/p>\n\n\n\n

Then, install the following packages to successfully bundle the dependencies and serve Ruby on Rails application development:<\/p>\n\n\n\n

  1. pkg-config:<\/li><\/ol>\n\n\n\n

    sudo apt install pkg-config<\/code><\/p>\n\n\n\n

    1. ffi:<\/li><\/ol>\n\n\n\n

      sudo apt install libffi-dev<\/code><\/p>\n\n\n\n

      1. clang GCC compiler:<\/li><\/ol>\n\n\n\n

        sudo apt-get install clang && rvm install ruby_version --with-gcc=clang<\/code><\/p>\n\n\n\n

        1. Libreadline 7 rather than libreadline 8<\/li><\/ol>\n\n\n\n

          sudo apt --fix-broken install <\/code>
          sudo apt-get install -y libreadline-dev<\/code><\/p>\n\n\n\n
