#!/bin/bash # Webmail with Roundcube # ---------------------- source setup/functions.sh # load our functions source /etc/mailinabox.conf # load global vars # ### Installing Roundcube # We install Roundcube from sources, rather than from Ubuntu, because: # # 1. Ubuntu's `roundcube-core` package has dependencies on Apache & MySQL, which we don't want. # # 2. The Roundcube shipped with Ubuntu is consistently out of date. # # 3. It's packaged incorrectly --- it seems to be missing a directory of files. # # So we'll use apt-get to manually install the dependencies of roundcube that we know we need, # and then we'll manually install roundcube from source. # These dependencies are from `apt-cache showpkg roundcube-core`. echo "Installing Roundcube (webmail)..." apt_install \ dbconfig-common \ php-cli php-sqlite3 php-intl php-json php-common php-curl php-ldap \ php-gd php-pspell libjs-jquery libjs-jquery-mousewheel libmagic1 php-mbstring # Install Roundcube from source if it is not already present or if it is out of date. # Combine the Roundcube version number with the commit hash of plugins to track # whether we have the latest version of everything. # For the latest versions, see: # https://github.com/roundcube/roundcubemail/releases # https://github.com/mfreiholz/persistent_login/commits/master # https://github.com/stremlau/html5_notifier/commits/master # https://github.com/mstilkerich/rcmcarddav/releases # The easiest way to get the package hashes is to run this script and get the hash from # the error message.
