Hi Xinyue,

I had a look but cannot reproduce this on either of my systems.
libGL.so.1 is correctly installed by update-alternatives when
mesa-diverted is configured.

Could you please install glx-diversions 0.7.1 and update-glx, and re-run

sudo update-glx --config glx (choose mesa-diverted)

and then paste the output of:

sudo update-glx --display glx


Kind regards,
