error: unsupported value for gpg.format: ssh – Debian

Trying to setup git commit signing on my Debian box. I already have this setup on my windows box and it works fine. Not so much on my Debian box. There I get the following error when I try to commit:

siggib@htzn:/var/www/phpdemo$ git commit -m "tweak"
error: unsupported value for gpg.format: ssh
fatal: bad config variable 'gpg.format' in file '/home/siggib/.gitconfig' at line 6

Here what my config looks like

siggib@htzn:/var/www/phpdemo$ git config --list
user.name=siggib@htzn
[email protected]
user.signingkey=ssh-ed25519 AAAAC3NzaC.....
gpg.format=ssh
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
remote.origin.url=https://github.com/siggib007/phptest.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
branch.master.remote=origin
branch.master.merge=refs/heads/master
siggib@htzn:/var/www/phpdemo$

I tried to google this and found nothing useful, also tried searching here with same results. Anyone have any good pointers for me?

    Turns out SSH signing is not available in the default git version in Debian 11. Had to follow this https://stackoverflow.com/a/74528937/8549454 to install a more up to date git version.

    SSH signing is only available with git>=2.34 (changelog). You likely have an older version.

    You can check like this:

    $ git --version
git version 2.25.1

    Update git

    If you are on Ubuntu, you can get a more recent version like this:

    $ sudo add-apt-repository ppa:git-core/ppa -y
$ sudo apt-get update
$ sudo apt-get upgrade
