Hi guys,

1. The discourse is running in a docker.

2. Here is the message that we see  
We’re currently on 2.9.0.beta5 but the current release (shown as critical to upgrade to) is 3.5.0.beta7.

3. If I run  
./launcher rebuild app

I am getting

x86\_64 arch detected.  
ERROR: Kernel version 3.10.0-1160.119.1.el7.x86\_64 not supported, please upgrade to at least 4.4.0

This is because the launcher is retrieving the latest build. What tag should I use for 3.5.0.beta7?

I assume when I will have the correct tag I can upgrade with the following command

./launcher rebuild app --run-image ‘discourse/base:’

I tried to look for the this info., but I could fnd anything.

Thank you beforehand.
