git refusing to merge unrelated histories on git push

The fatal: refusing to merge unrelated histories Git error occurs when two unrelated projects are merged (i.e., projects that are not aware of each other’s existence and have mismatching commit histories).

$ git pull origin main --allow-unrelated-histories

# Or master
# Or just try with origin

$ git pull origin main --allow-unrelated-histories

$ git add .
# Or file name

$ git commit -m "commited"

$ git push

--allow-unrelated-histories GIT HUB DOCS

By default, git merge command refuses to merge histories that do not share a common ancestor. This option can be used to override this safety when merging histories of two projects that started their lives independently. As that is a very rare occasion, no configuration variable to enable this by default exists and will not be added.
