How to update opengl driver in debian?

Question

linux

Put in debian steam, downloaded dota. I'm trying to run - asks to update opengl. I found a solution on the net ( askubuntu.com/questions/751324/failed-to-create-op... , added a repository, trying to update.
The system gives an error:

Failed to fetch https://pkg.tox.chat/debian/dists/nightly/InRelease  Unable to find expected entry 'bunsen-hydrogen/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)

I decided to remove unnecessary links in sources.list, I look:

# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160210-22:53]/ jessie contrib main non-free
# deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160210-22:53]/ jessie contrib main non-free

How to fix update error?

Answer 1

The problem is solved, I removed the MM flag in alsamixer and everything worked

Answer 2

As far as I know, either OpenGL comes with video card drivers. The same Nvidia with a proprietary driver pulls its GL .. (GLX)
So, I can hardly imagine how to "update" OGL outside the context of drivers.
Here is an example for nvidia
libgl1-nvidia-glx - NVIDIA binary OpenGL libraries
libgl1-nvidia-glx-i386 - NVIDIA binary OpenGL 32-bit libraries

PS! Does Debian have a PPA?
