希望此问题之前尚未被发布过，我已经在网上搜索解决方案。
我最近不得不擦除并重新安装驱动器分区上的 Ubuntu 20.04 LTS。之后，在通过 sudo apt-get 安装软件包时，我开始在安装底部遇到一个奇怪的错误。
在安装输出的最底部：
installed memtest86+ package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
memtest86+
E: Sub-process /usr/bin/dpkg returned an error code (1)```
A bit higher up, I get:
```pkg: error processing package memtest86+ (--configure):
installed memtest86+ package post-installation script subprocess returned error exit status 1```
```Processing triggers for man-db (2.9.1-1) ...
Errors were encountered while processing:
memtest86+
E: Sub-process /usr/bin/dpkg returned an error code (1)```
It does not affect the install in any way though. It still works fine.
Is this a serious issue, and how can I fix it?
