I'm using pass as my main password manager(which uses gpg2), but since a few days i can't create new keys, I always get the error message:
There is no assurance this key belongs to the named user [stdin]: encryption failed: Unusable public key
I already set the the trust of my key to ultimate als suggested here
And also checked that my key is not expired. Any suggestions how to fix this or should i get a new key?
