I'm new to Zimbra and new to Linux. Zimbra recently caught my eye due to the vast services it offers. I've been running hmailserver for almost 5 years for my side business and another small business that has 1 user is also using it. While running rainloop as webmail access. I really haven't had many issues with hmailserver since I started using it but I'm sure as most of you know it is very barebones. I was looking for a solution which offers not only mail but calendar access and file management. I'm currently running in an ESXi 6.5 environment. I installed Ubuntu 16.04 LTS and attempted to install the open source version of Zimbra. I ran across an error telling me the following:
ERROR: Installation can not proceed. Please fix your /etc/hosts file to contain:
<ip> <FQHN> <HN>
When I go into that file I have set all it has asked for and I am still getting the same error when I try to install again.
Thanks so much!
