How can I fix the error 'fatal: refusing to merge unrelated histories'?
This error occurs when Git sees no shared commit history between branches. Use `git pull origin branch-name --allow-unrelated-histories` to merge.
The 'fatal: refusing to merge unrelated histories' error often appears when attempting to merge branches or repositories that don’t share a common commit history, which Git interprets as unrelated. This can occur when creating a new repository with existing files or trying to combine two repositories into one. To bypass this restriction, use the --allow-unrelated-histories
flag with the git pull
command, as in git pull origin branch-name --allow-unrelated-histories
. This option forces Git to merge the two histories regardless of their separate origins, treating them as a single lineage moving forward. After the merge, you may need to resolve any conflicts if there are overlapping files or folders. Completing this merge with unrelated histories can simplify combining repositories but should be done carefully to maintain the project’s continuity.
