.. _lan-linux: .. _lan-linux-system: ================================ Trusting Your Start9 CA on Linux ================================ Here we will insert your Start9 server's CA certificate into Linux's trust store to ensure that applications will trust your Start9 server's services. .. tabs:: .. group-tab:: Debian/Ubuntu These instructions should work for Debian, Ubuntu, or any Debian or Ubuntu-based Linux, such as Linux Mint, PopOS, etc. Perform the following commands in the Terminal: .. code-block:: bash sudo apt install -y ca-certificates p11-kit .. note:: For each Mozilla-based application you plan on using, in order for them to trust your Start9 server's CA certificate directly from your Linux distribution's certificate trust store, execute the following command(s): If you use Firefox: .. code-block:: bash libnssckbiso=/usr/lib/firefox/libnssckbi.so && sudo mv $libnssckbiso $libnssckbiso.bak && sudo ln -s /usr/lib/x86_64-linux-gnu/pkcs11/p11-kit-trust.so $libnssckbiso If you use Firefox ESR: .. code-block:: bash libnssckbiso=/usr/lib/firefox-esr/libnssckbi.so && sudo mv $libnssckbiso $libnssckbiso.bak && sudo ln -s /usr/lib/x86_64-linux-gnu/pkcs11/p11-kit-trust.so $libnssckbiso If you use Librewolf: .. code-block:: bash libnssckbiso=/usr/share/librewolf/libnssckbi.so && sudo mv $libnssckbiso $libnssckbiso.bak && sudo ln -s /usr/lib/x86_64-linux-gnu/pkcs11/p11-kit-trust.so $libnssckbiso If you use Thunderbird (Useful for LAN access to NextCloud's calendar/contacts): .. code-block:: bash libnssckbiso=/usr/lib/thunderbird/libnssckbi.so && sudo mv $libnssckbiso $libnssckbiso.bak && sudo ln -s /usr/lib/x86_64-linux-gnu/pkcs11/p11-kit-trust.so $libnssckbiso If you performed any of the commands above, now we need to move the the mozilla apps' old trust store out of the way so the next time it starts it will use the system trust store: .. code-block:: bash mv ~/.pki ~/.pki.mozilla-old Finally, we will change directory to the folder where you downloaded your Start9 server's Root CA (usually `~/Downloads`), and run the following commands to add your Start9 server's CA certificate to the OS trust store: .. code-block:: bash cd ~/Downloads sudo cp ".crt" /usr/local/share/ca-certificates/ sudo update-ca-certificates In the output it should say ``1 added`` if it was successful. .. group-tab:: Arch/Garuda From the folder you have downloaded your Start9 server's Root CA, run the following commands (if you have changed the certificate's filename, be sure to change it here): .. code-block:: bash sudo pacman -S ca-certificates sudo cp ".crt" /etc/ca-certificates/trust-source/anchors/ sudo update-ca-trust Despite no output from the last command, you can test your app right away. .. group-tab:: CentOS/Fedora From the folder you have downloaded your Start9 server's Root CA, run the following commands (if you have changed the certificate's filename, be sure to change it here): .. code-block:: bash sudo yum install ca-certificates sudo cp ".crt" /etc/pki/ca-trust/source/anchors/ sudo update-ca-trust
