Rails Console error after upgrading to Ubuntu 18.04

Question

After upgrading from ubuntu 16.04 to ubuntu 18.04 I am receiving the following error when running rails console from the root directory of rails project. Only the console seems to be affected, I am able to start the puma server without issue.

Running via Spring preloader in process 23887

I've run bundle install and tried it with new rails projects with both Rails 5.1.6 and Rails 5.2

I also tried running RAILS_ENV=production bundle exec rails console

I'm using Ruby version:

ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]

Answer 1

Running the following code on the terminal solved the problem for me:

cd /lib/x86_64-linux-gnu
sudo ln -s libreadline.so.7.0 libreadline.so.6
