Hi Team,

I am trying to build docker container of triton-server with dali implemented.

I have downloaded the tar file "dali_backend-main.zip" and extracted the zip file then below step followed
$ cd dali_backend-main/
$ docker build -f docker/Dockerfile.release -t tritonserver:dali-latest .
//but I am facing below issue I am attaching the log segment where issue started.

Hi @akash2826 !

I see two problems here.

First of all, for some reason your system can't see ppa:deadsnakes repository. This issue is not related to dali_backend code. Probably you are behind some kind of proxy, which forbids you from accessing this recourse. This stackoverflow question briefly describes the problem. Therefore, there's not much we can help you with the Cannot add PPA: 'ppa:~deadsnakes/ubuntu/ppa'. ERROR: '~deadsnakes' user or team does not exist. error

Second issue, which you will face as soon as you resolve the proxy problem is how you download the code. dali_backend has some submodules inside, which are required for building, so you need to clone the repo recursively (instead of just downloading the zip). Please use git clone --recursive. The instructions show, how to build dali_backend properly.
