关于烦人且无用的“哦不。出了点问题”错误消息，有几个类似的问题，但是：
- 没有解决方案对我有用（见下文）
- 我无法物理访问该机器，只有 SSH 连接（或 Gnome 工作时的远程桌面...）
机器运行的是Ubuntu 22.04，登录时出现错误。我试过：
$ mv ~/.config ~/.config-backup && reboot
$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt --fix-broken install
$ sudo dpkg --configure -a
我很确定这是由 gnome 引起的，因为：
$ ls /var/crash
_usr_bin_gnome-shell.123.crash
$ sudo dmesg | grep error
