I just ran updates on my laptop... got error message:
Error while applying changes
pk-client-error-quark: Error while installing package: installed
bcmwl-kernel-source package post-installation script subprocess returned error
exit status 10 (313)
I lost all of my wifi card in my MacBook Air.
RECOVERY: For those like me, recovery can be a challenge. I didn't see how to
get back to a older kernel while working through rEFInd boot manager but
what got me out of this issue was.
- Open Additional drivers (Super Menu, type 'Drivers' and select).
- After scan for "Proprietery Drivers in Use"... switch option to "do not use
this device" and apply.
- Reboot and hopefully your Wifi is restored.
I then ran all updates (sudo apt update & sudo apt upgrade). I went
back to additional drivers and tried reinstalling... got error... but it
appears to have taken... even after reboot.
