Fail to clone repository with git lfs

Question

My repo uses git lfs. For a fresh clone, I ran:

git lfs install
git clone https://example.com/repo.git

The clone gets to the point where it starts downloading lfs files, gets to some file and then fails. The file at which it fails is different each time I attempt to clone. Very occasionally it succeeds.

Here is the output:

Cloning into 'repo'...

You can inspect what was checked out with 'git status'
and retry the checkout with 'git checkout -f HEAD'

The lfs logs say:

If I try git lfs pull at this point, everything works fine.

Any idea what could be causing this failure to download the lfs files?

Answer 1

I had the similar issue and there was already a bug reported with git lfs . While the bug was being resolved, this workaround helped me, where you skip the filter where it was failing.

// Skip smudge - We'll download binary files later in a faster batch
git lfs install --skip-smudge

// Do git clone here
git clone ...

// Fetch all the binary files in the new clone
git lfs pull

// Reinstate smudge
git lfs install --force

Answer 2

Try to do git lfs pull from GitBash.

It looks like the commandprompt isn't showing pass key popup, which is necessary for git lfs to work.

Answer 3

Git config settings

git config --global http.sslVerify true

git config --global http.sslBackend schannel

This worked for me
