A problem in isaac-sim:2022.1.0 docker image

[sunryang.kim]

Hello,
I have encountered a problem while using isaac-sim:2022.1.0 docker image.
I followed the instructions in “3. Advanced Installation”
I just ran “apt update” in docker container.
Does anyone know how to solve this problem?

I found that the file located in /etc/apt/sources.list has just one line.
I copied /etc/apt/sources.list of isaac-sim:2021.2.1.
Now I can run “apt update” and “apt install vim” etc.
