.bashrc: shopt: not found

The output you just posted indicates that you aren't actually running bash. This is why you are getting errors sourcing .bashrc.

To fix this problem, you need to check your login shell to make sure it's actually set to bash:

chsh -l

will list the available shells, and

chsh -s /path/to/bash

will change your login shell to bash.

Then logout and log back in.
