How do you force RoundCube to update or re-install via the command line?
/usr/local/cpanel/bin/update-roundcube --force
For Horde, the commands are;
/etc/init.d/mysql stop && /etc/init.d/chkservd stop mysqld_safe --skip-grant-tables & mysql >kill %1 /etc/init.d/mysql start /etc/init.d/chkservd start /scripts/fullhordereset
