答案1

我通过安装 libpam-kwallet4 libpam-kwallet5 解决了这个问题。

$ 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

答案2

您的日志表明存在问题/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

答案3

重建 pam 身份验证设置。转到另一个 TTY CTRL-ALT-F1，然后运行：

sudo pam-auth-update
# Make no changes and select "Ok" to update the config
sudo service lightdm restart

答案4

出现

$ sudo apt-cache search kwallet |grep pam

以及正在使用的任何 pam-kwallet 版本，但请使用与您的桌面管理器支持兼容性的版本。

紧随其后https://ubuntu.pkgs.org/20.04/ubuntu-universe-amd64/libpam-kwallet5_5.18.4.1-0ubuntu1_amd64.deb.html

安装的 libpam-kwallet5 就在这里...

$ ll /lib/x86_64-linux-gnu/security/pam_kwallet5.so

因此只需将此 pam_kwallet5 链接到您要求的 /lib/security/pam_kwallet.so 系统路径即可。

以下是您可能需要运行的命令，

$ sudo ln -sf /lib/x86_64-linux-gnu/security/pam_kwallet5.so /lib/security/pam_kwallet.so

然后尝试重新启动您可能需要的服务..

$ sudo service lightdm restart

如果$ journalctl -xe仍然出现错误，可能是没有找到 /etc/securetty，或者其他原因或权限失败，只需运行 mkdir 并在其上提供 chown 644

$sudo sh -c "mkdir /etc/securetty && chown 0644 /etc/securetty"

再次测试。快乐解决问题
