Public bug reported:

On a default Ubuntu Studio installation, when I try to render, even the
default scene (1 cube, 1 camera, 1 light) it crashes. Command line
output:

Ubuntu Studio is installed on a secondary partition, but installing
blender from the repositories on my main desktop, Xubuntu 20.04, results
in the same error.

When I download the binary from the blender website, it works.

System info:
Ubuntu Studio 20.04
Kernel 5.4.0-31-lowlatency

And:
Xubuntu 20.04
Kernel 5.4.0-33-generic

Graphics card is Nvidia GeForce GTS 250 with binary driver 340.
