error 403

When I build the image, some errors occur like:
Install KasmVNC server

So,how can i fix it

It looks like when you built the image you have changed the base container to ubuntu 22.04 (jammy) . We don't support this yet. You can see its trying to pull a jammy build for KasmVNC which is not available yet.

I'm sure the base image I'm using is nvidia/cuda: 11.3.0-devel-ubuntu20.04. I am trying to build CUDA 11.3 devel from the core image of KASM now.

The URL to download KasmVNC is dynamically generated based on the distro. I clearly see jammy in the KasmVNC URL where it should be focal if you are basing from ubuntu 20.04. Perhaps if you shared your dockerfile and build command that would help.

Thank you for your answer. I have found the cause of the error. I accidentally used the Ubuntu 22.04 repository when setting up mirrors.
