When I want to squash some commits by interactive rebase:

git rebase -i HEAD~3

And then:

pick cbd03e3 Final commit (signed)
s f522f5d bla-bla-bla (signed)
s 09a7b7c bla-bla (signed)

# Rebase c2e142e..09a7b7c onto c2e142e
...

The final commit haven't gpg-signature despite that all of those commits have same signature. Is it possible to retain commit gpg-signature after interactive rebase squash?

Like Cupcake stated, you can't retain the old signature from the unsquashed commits, but you can sign the new squashed commit if you rebase like this:

git rebase --interactive [email protected] HEAD~4

Adding [email protected] as an argument will sign the final squashed commit.
