I run ubuntu@16.04 on aws ec2.

Then wget the wowza installer@4.7.3 , installed it and get Segment Fault (core dump) error.

Here is what I found in /var/crash log.

I tried v4.7.1 and v4.7.0 , both of versions are crashed as well.

Really strange because I tried successfully yesterday.

All instructions

1. wget [https://www.wowza.com/downloads/WowzaStreamingEngine-4-7-0/WowzaStreamingEngine-4.7.0-linux-x64-installer.run](https://www.wowza.com/downloads/WowzaStreamingEngine-4-7-0/WowzaStreamingEngine-4.7.0-linux-x64-installer.run)

2. sudo chmod +x WowzaStreamingEngine-4.7.3-linux-x64-installer.run

3. sudo ./WowzaStreamingEngine-4.7.3-linux-x64-installer.run

Hello @yuanchieh cheng,

The first place to look for installation issues is in the installation logs. You can find them in /tmp/bitrock\_installer.log, as the root user, as described in this article:
