在用户密钥环中找不到签名，也许可以尝试交互式“ecryptfs-mount-private”

Question

我的 Ubuntu 13.04 在使用加密的用户帐户 USER1 时冻结。我重新启动，从那时起即使使用正确的密码我也无法登录到用户帐户 USER1。

我登录到用户帐户 USER2 以访问 TTY 并登录到用户帐户 USER1，我收到以下错误：

Signature not found in user keyring
Perhaps try the interactive 'ecryptfs-mount-private'

ecryptfs-mount-private
Enter your login passphrase:
Inserted auth tok with sig [xxxxxxxxxx] into the user session keyring

INFO: Your private directory has been mounted
INFO: To see this change in your current shell: User Home path

然后我从欢迎登录页面登录到用户帐户 USER1。我总是必须按照此过程登录到用户帐户 USER1。

有没有办法永久插入用户密钥环？
