Debian 10 自动登录 - lightdmcfg 存储库问题

我正在跟随 如何在 Debian 10 中自动登录？。正如截图所示，这最终指向了我安装的 Debian 10 无法找到的 Ubuntu 存储库。

有什么解决办法吗？

该包lightdmcfg仅接受precise或trusty代号。

该软件包已过时，不建议在 debian 上安装。

回答这个问题：

该gpg: no valid OpenPGP data found. 错误可以通过以下方法解决：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A3C2E0B93BF8E342
