Ubuntu 6.10 (Edgy Eft) Shell Changes
The Zimbra install scripts use 'source'.
Newer versions of Ubuntu (I think Edgy was the first) use 'dash' as the shell which doesn't have 'source'.
You will come across errors in your install log like:
Creating SSL certificate... *** Running as zimbra user: cd /opt/zimbra; zmcreatecert /opt/zimbra/bin/zmcreatecert: 27: source: not found Done
Change to using 'bash' and run install.sh and things should work:
sudo mv /bin/sh /bin/sh-old sudo ln -s /bin/bash /bin/sh
(You can also rm /bin/sh according to others)
