Automatic commit signing with SSH key?

[socketbox]

I've attempted to configure the automatic signing of commits in lazygit, but I've fallen short of the mark.

I can confirm that running git as follows signs a commit and that it appears as Verified in the GitHub user interface:

[2025-05-28 13:56:44]» git commit -S -m "My commit message"
bc7ef9ec6cda51d2d87eee8022c6b17ae5aa93a6
[main 890381a6c] My commit message
 1 file changed, 2 insertions(+), 2 deletions(-)

However, none of what I commit via lazygit is signed. Here is my (admittedly rather sparse) config file:

   1   │ gui:
   2   │   theme:
   3   │     selectedLineBgColor:
   4   │     - bold magenta
   5   │ 
   6   │ git:
   7   │   overrideGpg: true

The key I'm using is of type ssh-ed25519. In case it helps, here are the relevant portions of my .git/config file:

[user]
...
  signingkey = ssh-ed25519 <obfuscated>
...
 [commit]
   gpgsign = true
...  
  [gpg]
    format = ssh
  [gpg "ssh"]
     allowedSignersFile = /home/sockebox/.config/git/ssh_signers

This should work, I don't see anything wrong; except maybe the funny indentation of some of the git config sections. Did you copy/paste this verbatim? It might be the reason why it doesn't work.

If you have commit.gpgsign=true in the config, you shouldn't need -S on the command line.
