"When you install two different versions with dpkg or apt-get, it will not break the system, unless you use the -f option to force installation." of course it won't because it will refuse to do so to prevent break dependencies. Also, apt-get doesn't have
--force
, and dpkg has several
--force-*
but no
--force
. BTW, this will break any recent apache2, tomcat, subversion, uwsgi, in total 21 packages. —
