MQTT Binding not running in OH2 PaperUI after install in openHABian

But an MQTT Binding does not appear in the Inbox to or the Configurations menus.

This is normal, since the MQTT Binding is version 1.x.
Only 2.x Bindings are using the full feature set of OH2 (like Discovery in Paper UI, etc)
For example, the Network Binding is version 2.x and you can use the Inbox to add Things that have been discovered.

To use the MQTT Binding, you need to configure the /etc/openhab2/services/mqtt.cfg (not .conf) file and then define items that use it.

I have enabled the option in ‘Legacy bindings Add-on Management’ section, but no difference.

This will not have any effect in the case of MQTT since there is no 2.x version of the MQTT Binding. This options allows you to use a 1.x version Binding even if a 2.x version has been released.
