我最近安装了 ubuntu 桌面 18.04.4，在运行 python、nano 等不同程序时遇到了几个分段错误的问题。
系统日志如下所示：
Feb 4 18:50:04 dmcb-System-Product-Name kernel: [ 5368.279040] nano[12154]: segfault at 56956c2ce1e0 ip 000056056aa019d9 sp 00007ffd0396c478 error 4 in nano[56056a9f2000+3b000]

我目前正在调试此错误，但不确定问题是什么。由于分段错误随机来自不同的进程，我假设硬件是原因。一些见解确实有帮助。谢谢。

这是 sudo lshw -C memory 的结果：

我还没有完全解决问题，但我运行了 memtest82+ 发现有很多错误。我认为更换 RAM 是解决办法。
