1. When pushing with TortoiseGit, it prompts: the source refspec is ambiguous, as shown in Figure 1.
2. Analyzing the cause, it is because a branch and a tag with the same name exist simultaneously, named: fixbug-1.3.26-alpha.3, as shown in Figure 2.
3. Following the prompt, add refs/heads/ as a prefix to the branch, as shown in Figure 3.
4. Push succeeds, as shown in Figure 4.
Bash
git.exe push --progress "origin" refs/heads/fixbug-1.3.26-alpha.3:refs/heads/fixbug-1.3.26-alpha.3
