输入密码之后，无法登入桌面。无法执行sudo

# 使用sudo提权时出现如下错误
daryl@daryl-PC:~$ sudo su
sudo: PAM 认证出错：严重错误——立即中止
sudo: 需要密码

通过查看lightdm、dbus，定位到是deepin-authenticate.service的问题。

可通过执行 /usr/lib/deepin-authenticate/deepin-authentication 临时解决无法登录和sudo命令的问题。

23 还是 25？前置步骤是什么？换句话说，是什么操作之后导致了输入密码后无法登录桌面？

[ziqiangxu]

23，没有前置操作，或者我不知道。
出现这个问题之后我尝试升级apt update && apt dist-upgrade, 问题仍旧没有解决

23 还是 25？前置步骤是什么？换句话说，是什么操作之后导致了输入密码后无法登录桌面？

我回退到2024年8月的版本，这个版本是正常的。然后执行 apt update && apt dist-upgrade就会出现这个问题（无法执行sudo，提示PAM认证出错；无法登录桌面）

[BLumia]

回退是怎么回退的，装旧的iso吗？可以列一下升级升了哪些包吗？不然不太好排查。

是虚拟磁盘文件 vmdk。我已找到问题所在，是deepin-authentication占用了过多内存导致的。
/usr/lib/systemd/system/deepin-authenticate.service 文件里限定了MemoryLimit为100M，很奇怪，我这边内存占用竟然会达到惊人的687.8M
