Net_IDNA2: NOT OK Ubuntu, Nginx, and Roundcube Install

tyzenker · December 17, 2016, 12:14:42 AM

When I try to install Roundcube, it shows that I have a single error. It says, "Net_IDNA2: NOT OK(Failed to load class Net_IDNA2 from pear.php.net; See http://pear.php.net/package/Net_IDNA2)"

All my PHP and libraries seem to be installed. Below is a screen shot. Currently running Ubuntu 16.04 / Nginx.

Do you know how I can fix this?

What version of Roundcube are you installing?

According to some old Debian bugs it looks like the php5-intl package would handle the Net_IDNA2 class.

Version Levels:

php 7.0.8
Roundcube ver 1.2-beta

So, are you saying that I need to install the php 5 package along side php 7? So, I need both php versions running for this to work?

If php 7 doesn't have net_IDNA2 class, how would I get this to work?

Why you're installing beta if there are stable releases for this branch? Anyway, you need Net_IDNA2 which is a PEAR library or php-intl extension. Why don't you use composer?

Interesting. I will try it out. Thank you.

It turns out that it wasn't a true "Net_IDNA2" error. It was caused by a permission problem for two files:

1) config.inc.php
2) debian-db.php

I had to change the ownership of those files to the user that runs roundcube (it can differ depending on the install). After I changed the ownership of those two files, the "Net_IDNA2" error disappeared and the Roundcube page popped right up.
