hello  
i face below error when I run this command:sudo docker run --name 3ddart -p 80:80 -i -t 3d-dart  
docker: Error response from daemon: Conflict. The container name “/3ddart” is already in use by container “ae2958f5f25c0b8c9ca6e03fd49ba2dab3e7165dfb637e547b4221a154a0fd76”. You have to remove (or rename) that container to be able to reuse that name.  
See ‘docker run --help’.  
what is an error and how can I fix it?

Sounds to me like the answer to your question is already in the error message you sent.

Delete first the old container “ae2958f5f25c0b8c9ca6e03fd49ba2dab3e7165dfb637e547b4221a154a0fd76”

See ‘docker run --help’
