breeze installation, permission denied on a file

I want to install breeze on an existing project with a git repo built, i cannot install breeze there is an issue with a file that carries the same name or something.

Apparently i need to have permission to change the permission im not sure how to acess the terminal on vscode as root so ive tried using the ubuntu terminal and that doesn't seem to have an effect. Or maybe im doing it wrong.

This is how i initially tried giving access to sail user from the vscode terminal:

chown -R sail resources/views/post/view.blade.php
chown: changing ownership of 'resources/views/post/view.blade.php': Operation not permitted

then i learned i needed to create a group like this:

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:

if i check who belongs to the group their members are:

root@warpigs-desktop:~# grep /etc/group -e "docker"
docker:x:1000:root,sail

I want to eventually run this command:

sail@1d96dc64824f:/var/www/html$ vendor/bin/sail root-shell
Docker is not running.

but it says docker isn't running. i think i need to be able to run this command efficiently so that i can have access to the files and folders as "sail" and be able to change permission, that way i could finally get this over with. so what's wrong with it tell me, thanks.
