I installed iRedMail 0.98 on openvz with a Linux kernel of 2.6.32. At the end of installation it failed with nginx-full

E: Sub-process /usr/bin/dpkg returned an error code (1)


https://askubuntu.com/questions/764222/ … untu-16-04 (something like that)

what I did was apt purge apache2 and redo iRedmail.sh again and problem went away.

Re: E Sub Process Error

Try to install 'nginx-full' manually, then run iRedMail installer again.
Or, you can try our cloud deployment platform:
