error: 远程解包失败：index-pack abnormal exit 应该是某些文件超过了git限制。

解决

找了个脚本，非常好使：

REMOTE 改为你要推的远端，我本地仓库对应远端，实际使用改为了upstream，根据需要来

# Adjust the following variables as necessary
REMOTE=origin
BRANCH=$(git rev-parse --abbrev-ref HEAD)
BATCH_SIZE=100
 
# check if the branch exists on the remote
if git show-ref --quiet --verify refs/remotes/$REMOTE/$BRANCH; then
    # if so, only push the commits that are not on the remote already
    range=$REMOTE/$BRANCH..HEAD
else
    # else push all the commits
    range=HEAD
fi
# count the number of commits to push
n=$(git log --first-parent --format=format:x $range | wc -l)
 
# push each batch
for i in $(seq $n -$BATCH_SIZE 1); do
    # get the hash of the commit to push
    h=$(git log --first-parent --reverse --format=format:%H --skip $i -n1)
    echo "Pushing $h..."
    git push $REMOTE $h:refs/heads/$BRANCH
done
# push the final partial batch
git push $REMOTE HEAD:refs/heads/$BRANCH

保存成脚本，放到仓库根目录执行就可以。思想应该就是将仓库分成部分，分批push来解决
