今天早上在 CLEVO W253HU 上通过 wifi（Realtek RTL8188CE）开始。可能是因为昨天之前进行了更新，更多的飞行员管理，但不知何故昨天它工作正常。如果有人知道问题所在。

Ubuntu 需要很长时间才能启动（2 分钟）。
答案1
不知何故，您的内核模块无法找到所需的固件文件。引用您的日志：Failed to request firmware!
如果之前可以正常工作，则可能有某些原因导致软件包linux-firmware被linux-firmware-nonfree删除，甚至multiverseUbuntu 存储库的整个部分都可能被清除。
因此，请尝试再次安装这些软件包（然后重新启动 - 或重新加载内核模块）：
$ sudo apt-get install linux-firmware linux-firmware-nonfree
如果这没有帮助，也可以尝试这Debian 论坛帖子中通过移动固件文件的位置解决了同样的问题。
