bcmwl-kernel-source我在进行常规更新时遇到了一些问题。执行以下命令时，软件包出现问题sudo apt upgrade：
ERROR: Cannot create report: [Errno 17] File exists: '/var/crash/bcmwl-kernel-source.0.crash'
Error! Bad return status for module build on kernel: 4.15.0-24-generic (x86_64)
Consult /var/lib/dkms/bcmwl/6.30.223.271+bdcom/build/make.log for more information.
dpkg: bcmwl-kernel-source package processing error (--configure) :
the installed post-install script subprocess returned a status output error 10
Errors were encountered during execution :
bcmwl-kernel-source
E: Sub-process /usr/bin/dpkg returned an error code (1)
当我执行sudo apt autoremove或时sudo apt install -f，我得到了同样的事情。

更新：
从此链接执行命令后Ubuntu Wifi 驱动程序更新后无法正常工作，我的无线连接部分工作；我的连接不稳定。我使用它ssh和scp命令来与嵌入式系统（即接入点）一起工作，但不稳定的无线连接切断了管道
