# ### 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.
2014-07-08 00:37:53 +00:00
#
2014-09-21 20:05:11 +00:00
# 2. The Roundcube shipped with Ubuntu is consistently out of date.
2014-07-08 00:37:53 +00:00
#
2014-09-21 20:05:11 +00:00
# 3. It's packaged incorrectly --- it seems to be missing a directory of files.
2014-07-08 00:37:53 +00:00
#
# 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.
2014-09-21 20:05:11 +00:00
# These dependencies are from `apt-cache showpkg roundcube-core`.
