解決 qbittorrent docker版 libQt5Core.so.5丟失

背景

问题出在黑群晖上,群晖的系统其实也是Linux系统，只不过是闭源了，但是他的内核可能和社区的内核还是有点区别，导致它少点东西，有的时候在docker的应用方面会报错（以上个人理解，如有问题，烦请纠正）

我的设备以及环境

情况就是这样无法启动web面板，日志显示

因为我是在家里的实体服务器上进行操作，并不是在国内或者国外的服务器上进行运行的，这就会造成一个很麻烦的境地，

docker exec -it 容器id /bin/bash

进入容器后无法进行更新源，因为黑群晖这个docker的网络有问题，在使用ustc大学镜像源以后 居然会apt update失败,因为是在群晖里面的docker，我尝试了使用HTTP代理和Socket5代理进行apt的数据源进行更新（全都失败）

于是我想到一个更好更妙的方法，在路由器上全局科学，这样所有设备的网络都会通过路由器进行代理。

剥离 libQt5Core.so.5

首先进入容器

docker exec -it 容器 /bin/bash

更新源

apt update

安装binutils

apt install binutils

进行剥离

strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

退出容器

exit

重启docker容器

docker restart 容器
