git commit signing failed: secret key not available

Question

I am getting this error when trying to commit using Git.

gpg: skipped \"name \": secret key not available
gpg: signing failed: secret ke         


        

Answer 1

This worked for me on Windows 10 (Note that I use the absolute path to gpg.exe):

git config --global gpg.program "C:\Program Files (x86)\GnuPG\bin\gpg.exe"

This was the error I got prior to the fix:

gpg: skipped "3E81C*******": secret key not available
gpg: signing failed: secret key not available
error: gpg failed to sign the data
fatal: failed to write commit object

Answer 2

Using "C:\Program Files\Git\usr\bin\gpg.exe" was the solution for me.
Had to uninstall kleopatra. With it, it was not working.

So, summing up;

• No need for kleopatra, use GIT default instead.

• git config --global user.signingkey Y0URK3Y
  git config --global commit.gpgsign true
  git config --global gpg.program "C:\Program Files\Git\usr\bin\gpg.exe"
  

Answer 3

I had the same problem at it was that git name and email store in .gitconfig were different from the ones of the gpg key provided. I changed them in order to match and it started to work.

Answer 4

I'like to complete all these answers, cause I've got many issues with this.

These exemples use the --global flag, but you can remove it if you want to to these things locally.

Configure secret key in git

git config --global user.signingkey 35F5FFB2

Configure witch gpg program tu use in git (optional)

Some systems (Ubuntu for exemple) can have gpg and gpg2 at the same time. You need to specify you'll use gpg2

git config --global gpg.program gpg2

Export GPG_TTY (optional)

It is possible if you use these command in an ssh environment that you have the following error : Inappropriate ioctl for device or gpg: échec de la signature : Ioctl() inapproprié pour un périphérique. This can be fixed via :

export GPG_TTY=$(tty)

Auto enable GPG singing (optional)

git config --global commit.gpgsign true

Answer 5

What worked for me was adding

git config --global gpg.program "C:/Program Files (x86)/GNU/GnuPG/gpg2.exe"

If you want to find the full path of gpg2.exe:

where gpg2.exe

Answer 6

You need to configure the secret key before using it.

git config user.signingkey 35F5FFB2

Or declare it globally if you want to use the same key for every repository.

git config --global user.signingkey 35F5FFB2
