Issue while compiling smart contract - eosio.cdt

Question

I have installed eosio.cdt in Ubuntu system by using commands from EOS Developers Portal

wget https://github.com/EOSIO/eosio.cdt/releases/download/v1.4.1/eosio.cdt-1.4.1.x86_64.deb
sudo apt install ./eosio.cdt-1.4.1.x86_64.deb 

After that I have tried to compile the hello contract using eosio-cpp tool

#include <eosiolib/eosio.hpp>

using namespace eosio;

class [[eosio::contract("hello")]] hello : public contract {
  public:
      using contract::contract;

      [[eosio::action]]
      void hi( name user ) {
         print( "Hello, ", user);
      }
};

EOSIO_DISPATCH( hello, (hi))

I have tried to compile the code using

eosio-cpp -o hello.wasm hello.cpp --abigen

But it returns

/usr/opt/eosio.cdt/1.4.1/bin/clang-7: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /usr/opt/eosio.cdt/1.4.1/bin/clang-7)

Is there anything I am missing here?
