Git add . Gives me Bus error (core dumped)

问题

I am using ubuntu and trying to put my code on github but when I tried using the "git add ." command , I got an error "Bus error (core dumped)".

joannah@joannah-Inspiron-N5040:~/Macerdo$ git init
Initialized empty Git repository in /home/joannah/Macerdo/.git/
joannah@joannah-Inspiron-N5040:~/Macerdo$ git add .
Bus error (core dumped)
joannah@joannah-Inspiron-N5040:~/Macerdo$

I will appreciate any help.

For future reference .I solved this by creating a new folder and putting all my project files there and when I did a "git add ." and "git commit" it worked but I still do not know why the former failed to work. The good thing is at least I got a solution and moved on. That is most important. Thanks for the contributions.

This is how I solved this problem, assuming you can still run git diff:

Generate a diff patch
Remove repo
Clone repo again
Apply patch

git diff --patch > /tmp/patch.diff
cd ..
rm -rf my_repo
git clone <my_repo>
cd my_repo
patch -p1 /tmp/patch.diff

Have a look at dmesg. In my case this was due to a hardware error: A bad sector on my disk. :(

This might explain why the command worked after copying the files.

You should find something like this:

This happens to me quite often since my git repo is mounted via nfs, seems it times out and this causes a bus error sometimes.

The solution I found is to simply remove the lock files and continue on my merry way.

find .git -iname *.lock | xargs rm

In my case, a .py file had been corrupted and I got this message every time I tried to add it to a commit.

Deleting the .git / index.lock replaces the damaged file and everything is back to normal.
