This means that either a supervise process (started by `make
services/<name>/@supervise` or something that depends on that) is
still running, or the service is running somewhere else, even in
another branch (possibly invoked by `make services/<name>/@run`).

Try `fuser -v /run/lock/maas.dev.web` to see which process is still
holding that lock.
