Your issue seems different from Thomas' one. In your case: $ git cat-file -t refs/tags/linux-1.3.0 commit So the tag you mentioned is a _lightweight_ tag. These are not considered by git-describe by default. To make git-describe work, just do: $ git describe --tags $(cat .git/refs/tags/linux-1.3.0) linux-1.3.0 Franck
