How to resolve "Error: bad index – Fatal: index file corrupt" when using Git
This sounds like a bad clone. You could try the following to get (possibly?) more information:
git fsck --full
If the problem is with the index as the staging area for commits (i.e. .git/index
), you can simply remove the index (make a backup copy if you want), and then restore index to version in the last commit:
On OSX/Linux/Windows(With Git bash):
rm -f .git/index
git reset
On Windows (with CMD and not git bash):
del .git\index
git reset
(The reset
command above is the same as git reset --mixed HEAD
)
You can alternatively use lower level plumbing git read-tree
instead of git reset
.
If the problem is with index for packfile, you can recover it using git index-pack
.
I had that problem, and I try ti fix with this:
rm -f .git/index
git reset
BUT it did not work. The solution?
For some reason I had others .git folders in sub directories. I delete those .git folders (not the principal) and git reset
again. Once they were deleted, everything worked again.
You may have accidentally corrupted the .git/index file with a sed on your project root (refactoring perhaps?) with something like:
sed -ri -e "s/$SEACHPATTERN/$REPLACEMENTTEXT/g" $(grep -Elr "$SEARCHPATERN" "$PROJECTROOT")
to avoid this in the future, just ignore binary files with your grep/sed:
sed -ri -e "s/$SEACHPATTERN/$REPLACEMENTTEXT/g" $(grep -Elr --binary-files=without-match "$SEARCHPATERN" "$PROJECTROOT")
