I already have tag with name of "V1.8/INTERNAL", Then I'm trying to create the new tag with name of "V1.8" by using following command.
C:\Program Files\Git\bin\git.exe -C D:\IOT_GIT\WinPkg tag -a V1.8 3b87e27 -m "" --force
But, I'm getting the following error,
fatal: cannot lock ref 'refs/tags/V1.8': 'refs/tags/V1.8/INTERNAL' exists; cannot create 'refs/tags/V1.8'
When I saw in TortoiseGit the new tag created successfully. I don't know why this error is coming while creating that new tag.
