在 Ubuntu 24.04 中，如果我尝试将样式更改为 gtk2，qt5ct 会崩溃。我已经对此打开了一个错误。
但是，与此同时，有谁知道更改样式时 qt5ct 会更新哪些配置文件？我只是想让 virtualbox 在深色模式下工作。
帮助？
我正在使用 Ubuntu 附带的默认 Virtualbox 运行 Ubuntu 21.04。VirtualBox 图形用户界面版本 6.1.22_Ubuntu r144080。
它启动正常，但是当我尝试启动 VM 时，我得到：
Effective UID is not root (euid=1000 egid=1000 uid=1000 gid=1000) (rc=-10) Please try reinstalling VirtualBox. where: SUPR3HardenedMain what: 2 VERR_PERMISSION_DENIED (-10) - Permission denied.
所以，我尝试重新安装 Virtualbox。没有骰子，我得到同样的错误。所以，我尝试sudo chown 4755 /usr/lib/virtualbox/Virtualbox了，但后来我收到错误消息，说由于安全原因，以 root 身份运行是不可以的，这是有道理的。
那么，救命？有任何想法吗？
附加信息，如果我运行：
sudo virtualbox它似乎工作正常。
更多附加信息：
我在 Ubuntu 21.04 上针对 Virtualbox提交了一个错误。现在已确认。修复中没有预计到达时间。
我已经在 ZFS 上运行 20.04 w/root 几个月了，没有出现重大问题。
今天早上，我跑了一个apt dist-upgrade，我得到了以下错误：

帮助？
我已经在 18.04、19.10 和 20.04（测试版）中尝试过这个过程。
我在 ZFS 上安装 w/ Root，使用：
https://github.com/openzfs/zfs/wiki/Ubuntu-18.04-Root-on-ZFS
我擦除了整个磁盘（使用 BIOS 中的数据擦除），然后使用上面链接中概述的过程进行安装。一切顺利（使用 LUKS 加密，在 BIOS 中禁用安全启动，使用 UEFI 启动）。没问题。
我在安装结束时重新启动，我得到了 GRUB 菜单。我按 Enter 键启动 Ubuntu，然后屏幕变为空白，仅此而已。
我可以重新启动，然后通过 DELL 徽标返回，并获得 GRUB 菜单，仅此而已。
帮助？
编辑：
更多信息：
很难（几乎不可能）看到，因为笔记本电脑有 4k 屏幕，并且默认字体非常小，但我注意到在完全安装和第一次启动后，GRUB 菜单中只有一行，'UEFI固件升级'。
此外，作为此过程的一部分，当我这样做时：
update-initramfs -u -k all
和
update-grub
这两个都没有错误，但都没有产生任何输出，也没有像发生任何事情一样下降。
进一步编辑：
更多信息：
我正在从头开始重新运行安装。当我做：
root@ubuntu:/# update-grub
我得到：
