What versions of the Ubuntu Linux OS does Zimbra support?
We support Ubuntu 6.06 LTS (Long Term Support). This is the ‘enterprise’ version of Ubuntu and is officially supported by Canonical, the commercial arm of Ubuntu (this version will be supported by them for the next 3 – 5 years). When the next release candidate of “LTS” is available we will support it; the next candidate is likely 18 – 24 months out. There are newer versions of Ubuntu (eg 6.10) available in their community but we do not support or test against them. Users who wish to install ZCS on these newer OS’ obviously do so at their own risk.
