Dependencies resolved.

 Problem: cannot install both mesa-common-1:26.0.4-1mamba.x86_64 from rolling and mesa-common-1:26.0.3-1mamba.x86_64 from @System
  - package libmesa-1:26.0.3-1mamba.i586 from @System requires mesa-common = 1:26.0.3-1mamba, but none of the providers can be installed
  - cannot install the best update candidate for package mesa-common-1:26.0.3-1mamba.x86_64
  - problem with installed package libmesa-1:26.0.3-1mamba.i586

I have steam installed, which requires rolling-i586
