./install: $(...) does not contain bash script.

[dragon-dxw]

it looks like "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" is returning the command to bash to the console rather than to bash itself.

But if I copy the line to use wc instead of bash, that fails (with a zero length file after pressing Ctrl-D) and the bash line succeeds.

run wc "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" run arch -arm64e /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

(at least until a similar problem happens later on to install homebrew)

Interesting. This is pulled verbatim from Homebrew docs:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Ran the command locally and it behaves as expected.

But yes. I can reproduce when running the install script.
