h1. Collabora on Debian 11 natively

Install the necessary packages and repositories:

<pre>

sudo apt install gnupg

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 0C54D189F4BA284D

echo 'deb https://www.collaboraoffice.com/repos/CollaboraOnline/CODE-debian11 ./' | sudo tee -a /etc/apt/sources.list

sudo apt update

sudo apt install coolwsd code-brand hunspell

</pre>

Open the Collabora Online Server configuration file for editing:

<pre>

sudo nano /etc/coolwsd/coolwsd.xml

</pre>

Locate the <ssl> section in the configuration file.

Modify the <enable> and <termination> settings as follows:

<pre>

<ssl desc="SSL settings">

    <!-- switches from https:// + wss:// to http:// + ws:// -->

    <enable type="bool" desc="Controls whether SSL encryption between coolwsd and the network is enabled (do not disable for production deployment). If the default is false, must first be compiled with SSL support to enable." default="true">false</enable>        

    <!-- SSL off-load can be done in a proxy, if so disable SSL, and enable termination below in production -->

    <termination desc="Connection via proxy where coolwsd acts as working via https, but actually uses http." type="bool" default="true">true</termination>

</ssl>

</pre>

Save the changes and exit the text editor.

Restart the Collabora Online service to apply the new configuration:

<pre>

sudo systemctl restart coolwsd

</pre>

These instructions will install Collabora Online Server and configure the SSL settings as required. Don't forget to restart the service after modifying the configuration.
