Installation is missing index.html from iris

This is what happens when you install carbonio-ce.

apt install carbonio-ce

shows this error:

Configurando carbonio-auth-ui (0.1.1-0ubuntu4~) ...
cp: no se puede efectuar `stat' sobre '/opt/zextras/web/iris/carbonio-auth-ui/666cac3013c2c8f6365c711281fefba42202ad25/index.html': No existe el archivo o el directorio

That means that file could not be copied because it did not exist in the first place.

It does not affect normal Carbonio usage apparently.

Note: This Carbonio version was installed on 2022-01-13 from an Ubuntu 18.04 minimal installation.
