我使用通行证已经很长时间了；但是在将我的密钥存储和 gpg 密钥导出到另一台机器后，我看到以下输出：
$ gpg --list-key
/home/shved/.gnupg/pubring.gpg
------------------------------
pub 2048R/FA829B53 2015-04-28
uid [ultimate] Yury Shvedov (shved) <shved@lvk.cs.msu.su>
sub 2048R/74270D4A 2015-04-28
我的密钥已导入并受信任，但无法使用：
pass insert test
Enter password for test:
Retype password for test:
gpg: 2048R/FA829B53: skipped: No public key
gpg: [stdin]: encryption failed: No public key
fatal: pathspec '/home/shved/.password-store/test.gpg' did not match any files
我该怎么做才能再次使用我的密钥？
