Azure pipeline . Install sudo in ubuntu 18.04 docker container failed – Permission Denied

I am trying to run CI/CD in Azure pipeline .Because my app need some dependencies that only work ubuntu 18.04 however that VmImage version deprecated in Azure hosted agent. That is why I run it on ubuntu 18.04 docker container. It seem the docker container does not have sudo installed so I try to install it. Here is my pipeline code

  pool: 
    vmImage: ubuntu-latest
  container: ubuntu:18.04
  dependsOn: ImpactedProjects
  condition: eq(dependencies.ImpactedProjects.outputs['ImpactAnalysis.Project.Loyalty.QueryCachePopulator.AzureFunction.BddTests'], 'True')
  steps:
  - script: apt-get install sudo
    displayName: 'Install sudo'

However then I got this error

E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
##[error]Bash exited with code '100'.
Finishing: Install sudo

Is there anyone know how to fix this please. Thanks

    You will need to be the root user within the Docker container so you can install packages. If you’re running this with a docker run command, try setting the following environment variables as part of your docker run command:

    -e USERID=0 -e GROUPID=0

    I can reproduce the same issue when using the ubuntu 18.04 in Container job.

    enter image description here

    The cause of this issue is that this image runs as non-root, so for root-access things you have to switch into root.

    In a Dockerfile, you can simply switch user identities with a USER directive; this generally defaults to running as root:

    USER root

    To resolve this issue, you need to custom your docker image based on the image: ubuntu18.04.

    For example:

    FROM ubuntu:18.04
USER root
RUN apt-get update && apt-get install -y 
RUN apt-get install sudo
USER 1001

    Then you can use the custom image in container job.

    For example:

    pool: 
  vmImage: ubuntu-latest
container: 
 image: xxx/ubuntu18.04:23787
 endpoint: dockerserviceconnection
 options: --user root --privileged

steps:
- script: sudo apt-get install sudo
