LoadError: libffi.so.8: cannot open shared object file: No such file or directory running Rails

I am having trouble with creating a new rails project. When I run rails new project_name it comes to the rails webpacker:install it fails with the following error:

I am using ASDF for ruby version management.

I tried many solutions like uninstalling and installing the gem, running gem pristine and some other methods that are provided on SO and here.

Thanks to @Knud Larsen, this worked for me on Ubuntu 20.04:

wget
sudo dpkg -i ./libffi8_3.4.2-1ubuntu5_amd64.deb
