GPG fail to sign after rebooting

[Sylvain M]

Hi,

I face the following problem when I try to commit a signed one using SourceTree:

error: gpg failed to sign the data
fatal: failed to write commit object

I followed the instructions from Atlassian here: https://confluence.atlassian.com/sourcetreekb/setup-gpg-to-sign-commits-within-sourcetree-765397791.html

It worked until I restarted my computer (Mac). I tried to re install GPGTool, and it worked, until I rebooted again. I don't know what change when I reboot and I'm a bit stuck!

Any help would be welcome, thanks!
