git lfs issues

[ColdHeat]

Even with git subrepo it seems that we can sometimes have issues with git lfs.

❯ ctf challenge add ....
git-subrepo: Command failed: 'git read-tree --prefix=...... -u 4dda58e74a75de46c39............'.
Downloading .......file....... (.........)
Error downloading object: .......file....... (123456): Smudge error: Error downloading .......file.......  (.......hash.......): [.......hash....... ] Object does not exist on the server: [404] Object does not exist on the server

Errors logged to 'filename.log'.
Use `git lfs logs last` to view the log.
error: external filter 'git-lfs filter-process' failed
fatal: .......file.......: smudge filter lfs failed
Could not add the challenge repository. Please check git error messages above.

You can work around this with the following and then manually pulling the lfs files as referenced in the lower links

export GIT_LFS_SKIP_SMUDGE=1

We should still try to have a better flow for these large files though.
