Comment 0 for bug 1625878

I'm trying to import 2015.1.4 tag from Nova project.
This tag also matches an existing tag: kilo-eol.

To import a specific tag, I created a temporary branch:

  git branch temp-import/2015.1.4 2015.1.4

I can import (without merge) just fine:

  git-upstream import --no-merge temp-import/2015.1.4

When finalizing the import:

  git-upstream import --finish --into local/kilo --import-branch import/2015.1.4 temp-import/2015.1.4

I get this error:

  Searching for previous import
  Merging import to requested branch 'local/kilo'
  ERROR : Failed to finish import by merging branch:
      'import/2015.1.4'
  into and replacing the contents of:
      'local/kilo'

  ERROR : 'git merge --no-commit -s ours import/2015.1.4' returned with exit code 128
  stderr: 'fatal: import/2015.1.4 - not something we can merge'

I end up with those branches being created:

  import/kilo-eol
  import/kilo-eol-base

Instead of the "expected" branches with import/2015.1.4 prefix.
