error: failed to parse manifest at `/var/www/node-template/node/Cargo.toml`

Caused by:
  failed to parse the `edition` key

Caused by:
  this version of Cargo is older than the `2021` edition, and only supports `2015` and `2018` editions.

my env:

Ubuntu 22.04 LTS
rustc 1.62.1 (e092d0b6b 2022-07-16)
cargo 1.62.1 (a748cf5a3 2022-06-08)

docker-compose.yml file in the root directory seems to be using an outdated Docker image that has an old version of Rust. Replace the following line in that file:

image: paritytech/ci-linux:974ba3ac-20201006


image: paritytech/ci-linux:42a94a57-20220730

and try running ./scripts/docker_run.sh again. It should build and start fine.

You can also use the following for the latest version always:

image: paritytech/ci-linux:production

Rest of the tags for the image are here. And here is the related issue in the repo.
