How to install them? When I start rendering a scene, I get this: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.28' not found (required by ./Blender_K-cycles_linux/blender) /lib/x86_64-linux-gnu/libm.so.6: version 'GLIBC_2.29' not found (required by ./Blender_K-cycles_linux/blender)
Is it even possible to install it?
No. Instead you should obtain a version of
blendercompiled for your target environment (current Google Colab appears to use Ubuntu 18.04).See also this answer.
