Same here. Hitting C-g at the password prompt is not sufficient to
trigger the error for package installation.

Maybe you could use something else? "emacs -Q /ssh::" did the failing
test.

I'm running a recent build of "GNU Emacs 27.2.50 (build 1,
x86_64-pc-linux-gnu, GTK+ Version 3.24.27) of 2021-03-28" on Fedora
33. But I don't believe it matters.

The point seems to be that default-directory is remote, when you call
list-packages, and try to install Tramp 2.5.0.3. Emacs completely blocks then.

I have seen also other error messages during Tramp package compilation,
which I'm not able to reproduce just now. But let's fix the first
problem first.
