Hi Anatoli,
There is a problem with your apt sources according to your screenshot. The 460.84 driver from 20.10 conflicts with the 460.80 driver from 21.04
Have a look in the other software tab in Software & Updates, where you might have the graphics-driver PPA enabled and set to groovy.
Either disable it so you get the driver from the normal Ubuntu repositories, or set the distribution of the PPA to hirsute.
