Answer 1

我通过安装 libpam-kwallet4 libpam-kwallet5 解决了。

$ sudo apt-cache search kwallet |grep pam
libpam-kwallet4 - KWallet (KDE 4) integration with PAM
libpam-kwallet5 - KWallet (Kf5) integration with PAM
$ sudo apt-get install libpam-kwallet4 libpam-kwallet5
$ sudo service lightdm restart

Answer 2

您的日志表明/lib/security/pam_kwallet.so. 您能否确定该文件是否仍然存在，您可能需要重新加载 kwallet：

sudo apt-get purge kwalletmanager
sudo apt-get install kwalletmanager
