Kernel needs upgrading but that's not an option right now

Installation
1

I am in charge of support for a legacy forum. Once a year SSL certificates need upgrading and I follow a recipe that was handed to me by the previous admin.
The last step is ./launcher rebuild app
This year it downloaded the newest version but then complained about Kernel
x86_64 arch detected.
ERROR: Kernel version 3.10.0-957.27.2.el7.x86_64 not supported, please upgrade to at least 4.4.0

The Kernel upgrade is not an option for now.

I have attempted to set the forum version to the one we are currently running (bye bye upgrades!) by editing app.yml and setting the version line (also uncommenting it)
version: 2.9.0.beta7

This time it did not attempt to download that specific version and I still get the kernel complain.

How can I go back to before my first attempt? I’m guessing I need to switch the head in the git folder, but so far I have been unable to figure out where the repo is kept on disk.

Found this thread : kernel-version-upgrade-required-when-manually-updating-discourse
I will attempt to bypass the check and hope for the best. However my question as to how to revert is still valid.

If you only need to update the SSL certificate you don’t need a rebuild. Update the files and restart the nginx from inside the container, or just restart the container.

Now I see this… A whole year later, after spending hours on this issue. I’m adding this to the notes left from the previous maintainer. It would be so much simpler if it works! (No reason it shouldn’t)

Thanks!
