In ubuntu hardy heron, wine runs into a new security setting that disables 16-bit applications. When you try to install them, you get an error:
preloader: Warning: failed to reserve range 00000000-60000000winevdm: unable to exec '--app-name': 16-bit support missing
On ubuntuforums is a solution which actually works:
sudo sysctl -w vm.mmap_min_addr=0

Describes how to create a subdomain, install Wordpress, copy your content, and prevent search engines from finding your sandbox.
When starting a new program on, for example KUbuntu 8.04, there is a delay of several seconds. This can be caused by SCIM — which is a multi-language keyboard input protocol — not loading. Check your system logs. If this is the problem, try as root:
apt-get remove scim-qtimm scim-bridge-client-qt4 scim-bridge-client-qt scim-bridge-client-gtk scim-bridge-agent skim scim-modules-socket libskim0 libscim8c2a
