So I originally commit something which included files that weren't meant to be included. I wasn't sure of how to undo it, so I came across this post (How to undo the last commits in Git?) and followed the advice of the second highest answer Kyralessa and typed in:
git reset --hard HEAD~1
What this did was reset my local repository to an older commit (about ~10 commits ago).
So I tried resetting my local copy to the latest commit.
git reset --hard <commit>
Which brings up the following error message:
fatal: ambiguous argument '53430f0': unknown revision or path not in the working tree.
I'm not really sure why as I know that this is the last commit made.
So I then just tried making my local copy match exactly what's in my remote one I meant to write these two commands:
git fetch origin
git reset --hard origin/master
But after I type the first (fetching the origin), it tells me this:
remote: Not Found
fatal: repository <url> not found
I'm not really sure how it can say this as the repository is definitely there. I mean I'm on it right now.
I imagine it all stems from the initial command I ran but I have no idea what could have went wrong.
EDIT: This was all just a stupid mistake on my part. Apparently I was in of the subdirectories of my repository the whole time (and even for the second time I tried everything).
