和其他人一样，我在使用 Ubuntu 20.04 时也遇到了随机崩溃。我重新安装了 Ubuntu，但崩溃仍然继续。有时我可以连续几天不出现问题，有时一小时内又会出现这种情况。
在网上搜索发现其他人也有同样的问题，但是 ask Ubuntu 提供了最好的答案，所以我会在这里问。有人给出了一个特别好的建议：
sudo journalctl -r -p err
这给了我看似正确的崩溃时间:(抱歉格式不对，终端输出太长，我无法让它看起来很好）

重复的消息是 ilan-AM1M-S2H 内核：Initramfs 解压失败：解码失败，但它发生在崩溃前 1-2 分钟，对我来说这看起来有点长。
在最近的 2 次崩溃中，它似乎与蓝牙有关，但我的这台机器上没有蓝牙。奇怪……在其他情况下，它声称网络问题。我不知道发生了什么，但 Ubuntu 给了我正确的命令来应用。现在我需要了解我可以对解压失败做些什么，如果这确实是问题所在。
在其他随机崩溃的情况下我都没有找到解决问题的方法，但 sudo journalctl -r -p err 是一个非常强大的工具，也可能会对其他人有所帮助。
尽管错误消息之间间隔很长，但如果您能提供任何建议，说明问题是否确实出在解包失败上，我将不胜感激。同样，我可以做些什么来使解包成功。
编辑：我在笔记本电脑上查找时找不到这个问题。我想也许我忘了发布它？无论如何，回到我的桌面后我又找到了它。与此同时又发生了 2 次崩溃，几乎是接连发生的。这次的日志是：
Failed to get journal fields: Cannot assign requested address

看起来像是另一个假蓝牙，之前有一个我没见过的错误。有人能告诉我发生了什么吗？似乎某个特定线程超时了，但这会导致整个系统崩溃吗？超时应该表现得正常而不是崩溃？？

答案1
我想我可能发现了两个问题：
它试图调用蓝牙，而我的硬件没有蓝牙。这是通过以下方法解决的：https://www.linuxquestions.org/questions/ubuntu-63/how-to-remove-bluetooth-4175678356/
总是出现错误：Initramfs unpacking failed: Decoding failed 这个可以通过以下方法解决 https://www.youtube.com/watch?v=7sAdA3XmUZ8
