Git LFS: Error: failed to push some refs to

Question

I installed LFS for git, and when I try to push I get this error:

How can I fix this?

Answer 1

tl;dr

git config --global lfs.contenttype 0

Elaboration

I had the same problem, but non-LFS uploads were fine so it wasn't the server nor infrastructure blocking big files or anything.

After some searching about, I found this advice on GitHub:

It looks like you're using a Bitbucket Server instance. Could you try running the command git config lfs.contenttype 0 and then try with 2.6.0? Some versions of Bitbucket Server want a certain Content-Type header, and setting that option should help Git LFS provide the header it wants.

After running that command, now my repo works great with LFS! 👍🏼

I did have to run that command for each repo that uses LFS. I tried the variant command git config --global lfs.contenttype 0 and that seems to have taken care of all the rest of my repos. Now I have no problem using LFS anymore 🙌🏼

Answer 2

It seems the GitHub server you are trying to push to has set a file size limit of 100 MB.
Solution: install LFS in your local repository and start tracking these files with LFS.
Since you've already committed the large files, you either:
1. git reset --mixed <commit_before_adding_the_large_files>, then install LFS in your local repo, track the files and commit the changes
OR
2. git commit --amend, then install LFS in your local repo, track the files and commit the changes

Additional info: git reset; git commit --amend
