Apache 2.4.18 Ubuntu 16.04 not enabling HTTP/2 module?

Question

Apache HTTP Server

Many times I come across that in Apache 2.4.18 there is no http2 module, while the official source says that the module is available from version 2.4.17 and higher.
During installation, it displays an error message:

sudo a2enmod http2
ERROR: Module http2 does not exist!

I searched in the information, according to the link on stackoverflow , the user Jordi had the same problem.
The suggested solution is to update apache to 2.4.25 from the following repository:

$ sudo add-apt-repository -y ppa:ondrej/apache2
$ sudo apt-key update
$ sudo apt-get update

$ sudo apt-get --only-upgrade install apache2 -y
$ sudo a2enmod http2

And yes, it really works, but!
After this update, I often get "An error was detected in the system program."
Got into /var/crash, and there is error data in apache:
_usr_sbin_apache2.0.crash
The link contains the full text of the error.
And also got into the Apache logs, there is such a picture:

Advise whether it is worth updating Apache on the production server in this way to enable http2?
I've read that these kinds of bugs are minor, and a couple of times they even lower the bug level in Apache itself to stop such bugs from popping up.
And yet, how can you enable http2 without risks?
