gpg: There is no assurance this key belongs to the named user

[Matthias Apitz]

Hello,

I wanted to insert a new password into my password store, but I can't do
so anymore. It says:

$ pass insert -m web/test3
Enter contents of web/test3 and press Ctrl+D when finished:

gpg: 61F1ECB625C9A6C3: There is no assurance this key belongs to the named user
gpg: [stdin]: encryption failed: Unusable public key
Password encryption aborted.

I can decrypt fine anything in the password store:

$ gpg2 -d ~/.password-store/web/test2.gpg
gpg: encrypted with 4096-bit RSA key, ID 61F1ECB625C9A6C3, created 2017-05-14
      "Matthias Apitz (GnuPG CCID) <guru at unixarea.de>"
4711
0815

but encryption seems to be the problem:

$ gpg2 -ea -r "Matthias Apitz (GnuPG CCID) <guru at unixarea.de>" file
gpg: 61F1ECB625C9A6C3: There is no assurance this key belongs to the named user

sub  rsa4096/61F1ECB625C9A6C3 2017-05-14 Matthias Apitz (GnuPG CCID) <guru at unixarea.de>
 Primary key fingerprint: 5E69 FBAC 1618 562C B3CB  FBC1 47CC F7E4 76FE 9D11
      Subkey fingerprint: EB62 00DA 13A1 9E80 679B  1A13 61F1 ECB6 25C9 A6C3

It is NOT certain that the key belongs to the person named
in the user ID.  If you *really* know what you are doing,
you may answer the next question with yes.

Use this key anyway? (y/N)

What might be the problem in my $GNUPGHOME:

I have enough older backups of this part of my $HOME, but would like to
understand what is missing or damaged, and how it happened, and how to
fix it.

Thanks
