If you use for RPM installation parameter -i while there is already a
different version installed, rpm just does what you tell the tool: it
will install in parallel. Sometimes this is wanted, in most cases you
instead want "rpm -U". But the decision is made by _you_.

If you are sure libxslt-1.0.33 is not needed and replaceable by
libxslt-1.1.2 then you can use apt for uninstallation. See "apt-get
--help" for command remove. Like with installations it will check for
dependencies during remove too. Be cautious what will be uninstalled!
You can for safety first run "apt-get remove -s libxslt-1.0.33-2".
