I have installed roundcube on wheezy using https://www.howtoforge.com/using-roundcube-webmail-with-ispconfig-3-on-debian-wheezy-apache2 However the package roundcube is not available on jessie. How to migrate? Using the package from stretch? Thanks, Yves
I guess I would install roundccube from source. Roundcube is a normal php web application, so you can run it within a normal php enabled website in ispconfig, create e.g. a new website webmail.yourdomain.tld and a database in ispconfig, then download roundcube into the web directory of that site and follow the installation instructions of the roundcube installer.
