I am trying to fresh-install the latest iRedMail on Ubuntu 16.04 LTS, and I am stuck in the process. Since it's a fresh install, some of the required info above is not available.

I am following the instructions in this link: http://www.iredmail.org/docs/install.ir … untu.html. I have completed all the steps successfully before the "Start iRedMail installer" step.

Next, when I tried this command (Since I am in China, I used IREDMAIL_MIRROR as instructed in the link):
sudo IREDMAIL_MIRROR='http://42.159.241.31' bash iRedMail.sh

I get output from terminal:
< SKIP > Function: check_new_iredmail.

It seems to me that iRedAPD-2.0.tar.bz2 and iRedAdmin-0.7.tar.bz2 are missing. What can I do to fix this?

Thanks!
