MySQL at this moment does not support IPv6 connections, but the development versions seem to support it (sort of). There are tools to make it work, such as https://twiki.cern.ch/twiki/bin/view/EGEE/IPv6CARE.

|---|
bind-address = '::' |
apt-get
security.ubuntu.com does not work, so no security updates. Workaround: use local mirror nl.archive.ubuntu.com for security updates.
