I have a rather old laptop, which has a Intel Core duo 2 processor
and I was not able to run the Dolphin Emulator or any games from steam that I wanted because I needed a minimum of OpenGL 3.1 .
I ran the oibaf PPA and now I have Mesa 11.2 installed
$ glxinfo | grep "OpenGL version"
OpenGL version string: 2.1 Mesa 11.2.0-devel (git-56fc298 2016-01-12 wily-oibaf-ppa)
is there a possibility to upgrade my OpenGl version to 3.1?
and if yes which steps do i have to take. (pls give me commands 😀 )
In addition, i'd like to ask if i need to take any more steps so that these error messages won't show up, or will they be solved once I run OpenGL 3.1?

well maybe your hardware does not support OpenGL 3.1+, but there is a workaround. You can use Software Rendering (LLVMpipe). In order to do that you have to run:
where command is your program of choice. Example:
On steam you should put in Right Click on Game->Properties->Set Launch Options
However the games might (and will) run slow! It is strongly recommended to buy a new laptop/ update your graphics card.
At this point of time LLVMpipe supports up to OpenGL 3.3.(NOTE: i have Ubuntu 14.04 and lower mesa version than you)
