我通过 CLI(从另一台设备)更新了以下软件包,现在 Ubuntu 启动后,我只看到一个黑屏......
apparmor/jammy-updates 3.0.4-2ubuntu2.2 amd64 [upgradable from: 3.0.4-2ubuntu2.1]
gnome-remote-desktop/jammy-updates 42.7-0ubuntu1 amd64 [upgradable from: 42.0-4ubuntu1]
grub-efi-amd64-bin/jammy-updates 2.06-2ubuntu14.1 amd64 [upgradable from: 2.06-2ubuntu10]
grub-efi-amd64-signed/jammy-updates 1.187.3~22.04.1+2.06-2ubuntu14.1 amd64 [upgradable from: 1.182~22.04.1+2.06-2ubuntu10]
libapparmor1/jammy-updates 3.0.4-2ubuntu2.2 amd64 [upgradable from: 3.0.4-2ubuntu2.1]
shim-signed/jammy-updates 1.51.3+15.7-0ubuntu1 amd64 [upgradable from: 1.51+15.4-0ubuntu9]
问题是,我不确定是哪个原因导致了这个问题,而且我在任何日志文件中都找不到任何跳出的内容。大概是与有关,gnome-remote-desktop
但我不确定。
有人知道我该怎么做才能找出问题所在,以便确定如何修复它吗?
如果有任何相关性的话,我的 VNC 连接也已停止工作并且现在超时 - 如果 GUI 不工作的话,我想这并不奇怪。
编辑
我回滚了gnome-remote-desktop
软件包并重新启动,但没有什么变化。我尝试对每个软件包执行相同的操作,但由于依赖性问题,它不允许我回滚 grub 软件包,shim-signed
也无法回滚(见下文):
