Installing a root/CA Certificate

Given a CA certificate file foo.crt, follow these steps to install it on Ubuntu:

    1. Create a directory for extra CA certificates in /usr/local/share/ca-certificates:

     sudo mkdir /usr/local/share/ca-certificates/extra

   2.  Copy the CA .crt file to this directory:

    frist go to where the .crt file is and then open terminal

     sudo cp foo.crt /usr/local/share/ca-certificates/extra/foo.crt

     sudo cp squid2.crt /usr/local/share/ca-certificates/extra/squid2.crt

   3.  Let Ubuntu add the .crt file's path relative to /usr/local/share/ca-certificates to /etc/ca-certificates.conf:

     sudo dpkg-reconfigure ca-certificates





















sudo cp squid2.crt /usr/local/share/ca-certificates/extra/squid2.crt
