# ### 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 The Roundcube shipped with Ubuntu is consistently out of date.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`.
