building the docker image fails on ubuntu 23.10

[steliospaps]

When I run the command in the README it fails: ` $ docker build -f Containerfile.install -t "keepass-diff:custom-local" . DEPRECATED: The legacy builder is deprecated and will be removed in a future release. Install the buildx component to build images with BuildKit: https://docs.docker.com/go/buildx/

Hi, the solution is to get rid off the username, e.g. by this command in the main directory:

sed -i -e 's/rust:rust/root:root/' Containerfile.install

[stdedos]

... or remove the instruction altogether, since root can touch everything.

Would upstream accept PRs?

Similar issue on Mac OS using podman for building:

podman build -f Containerfile.install -t "keepass-diff:custom-local" .
