Can't push to GitHub? (error: git-lfs died of signal 11)

Question

After I've updated my Mac to ver. 10.13.3 (17D47) I can't push to GitHub.

I get the following messages:

error: git-lfs died of signal 11
error: failed to push some refs to 'https://github.com/USERNAME/REPO.git'

I've trying deleting my SSH key on GitHub create new on the Mac and reconnecting it again with no effort.

Also, created .ssh/config file with the following:

Host *
AddKeysToAgent yes
UseKeychain yes
IdentityFile ~/.ssh/id_rsa

and still get the same two errors when trying to push.

Any help is welcome.

Answer 1

Ok, so this was solved, finally and GitHub looks green again after many days of local work :)

The problem was git-lfs (Git Large File Storage) and because it was blocking large files for uploading the second error was also shown.

1) I've uninstalled git-lfs from my system with the following commands because apparently there is not yet an uninstaller.

$ git config --global --unset filter.lfs.required
$ git config --global --unset filter.lfs.smudge  
$ git config --global --unset filter.lfs.clean 

# confirm all git lfs settings are gone
$ git config -l | grep lfs

1.1) This did not remove it completely, by using the command:

which git-lfs

Locate the folder where it is, then use the Finder > Go > GoToFolder... and enter the path to find it, then just move it to trash from there.

2) After that, simply re-install it with Homebrew, run:

brew install git-lfs

2.1) I installed git-lfs previously before the uninstall hoping that will auto-reinstall it, but that did not happen and after running the command, Homebrew says git-lfs is installed but is not linked and by running:

brew link git-lfs

git-lfs is linked and the problem is solved .

Hope this helps anyone in the future.
