Am I supposed to run BFG on the mirrored repo or the original?
I want to delete two files from my git repo that aren’t there anymore.
I put them in, committed, and tried to push but they were too large. So I took them out, and kept working, then committed, tried to push, but it still gave me the same error. I figured they’re still in the history somewhere.
I think I made the problem worse because I kept working in that branch and made 1 more commit. Then I merged that branch back to the master branch.
So I searched for a solution and found bfg.
But the instructions on the page don’t make sense to me.
$ git clone --mirror git://example.com/some-big-repo.git
Where am I supposed to clone from? My remote repo on github.com doesn’t have the commits and the merge I did since I added the large files. But the instructions make it seem like I’m supposed to get it from there anyway. (I cloned from my local repo.)
$ java -jar bfg.jar --strip-blobs-bigger-than 100M some-big-repo.git
some-big-repo.git the mirrored repo or the normal local repo?
(I used the mirrored repo for this.)
And then I checked that my history had been updated and tried,
$ cd some-big-repo.git $ git reflog expire --expire=now --all && git gc --prune=now --aggressive
(I was in the mirrored clone for this) I got an error.

[remote rejected] master -> master (branch is currently checked out) error: failed to push some refs to '/home/cole/main_repo'
This makes sense to me. Yeah I do currently have
master checked out. But then, what else was I supposed to do? I can only see problems happening if I try it another way.

You should clone/mirror the repo that you eventually plan to replace the commits-in, but there’s an underlying assumption that this repo is also a bare repo. This would usually be a remote repo, but you might also clone a local repo to save bandwidth.
The underlying assumption is that the repo where you will eventually store your cleaned repository is also a bare repo. Server-based repos e.g. GitHub are usually exactly that.
In your case it sounds like you have cloned a local, non-bare (contains a HEAD and working-copy) repo, either to save bandwidth, or because it is the repo that contains the commits you wish to clean. Either way, in order to push back into a non-bare repo, you need to make sure you don’t have any refs you want to push checked-out, including master.
From your comment it looks like you found the solution, which is to push-back to the eventual origin repo, which will likely be a bare repo.
