Partial clone - bad pack header?

[Luke Diamand <luke@diamand.org>]

I tried to do a partial clone, but it gave me a "bad pack header". Is
there anything I can do to debug this?

I did "git config uploadpack.allowfilter true" in my repo.
Then I went to a scratch directory and did:
$ git clone --filter=blob:limit=10M ssh://localhost/~/git/my_big_repo

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

fatal: the remote end hung up unexpectedly
fatal: protocol error: bad pack header
warning: Clone succeeded, but checkout failed.
You can inspect what was checked out with 'git status'
and retry the checkout with 'git checkout -f HEAD'

$  git checkout origin/master
fatal: the remote end hung up unexpectedly
fatal: protocol error: bad pack header

$ git --version
git version 2.20.1.611.gfbb209baf1

There's plenty of disk space left.

Thanks,
