I'm trying to use interesting password management tool named Pass.

I did the following:

1. Installed gpg tool $ sudo dnf install gpg
2. Generated a key using $ gpg --gen-key
3. Typed $ pass init "foobar id of my gpg key" as stated here
4. Got

mkdir: created directory ‘/home/chichivica/.password-store/’ Password store initialized for foobar@email.com

5. Tried to add a simple password

$ pass insert foo Enter password for foo: Retype password for foo:

6. And there is the problem

gpg: A45A123C: There is no assurance this key belongs to the named user gpg: [stdin]: encryption failed: Unusable public key

Could anyone give me some advice?
