GPG key expired

[NicoHood]

Your key expired as you can see in this commit:
01b7237

You need to update it, publish it to the keyservers and possibly update the github profile. But i would not edit the github profile unless you need to. Otherwise it could make every commit so far unverified again (permanently). At least thats what i remember from the docs.

It wasn't expired (I renewed in Jan). I had to delete the key from Github and re-add for it to recognize it, but its fixed now
