iMac 27 inch late 2013 Kubuntu 20.04 update problems
by tifkat from LinuxQuestions.org on (#5D13P)
Greetings,
Let me start by saying I tried to search for iMac and Mac here in the Ubuntu forum, but got a database error page each time.
I have rescued a late 2013 iMac 27 inch from work and have installed Kubuntu 20.04 on it successfully. Everything works 'out of the box.' I did select to install proprietary 3rd party drivers during install.
I configure my wireless network connection and Diskover finds updates available. I update and reboot, only to be greeted with a ShimX64/grubx64 issue.. easy enough to fix after a brief search... but even after fixing that (and when it boots through the error anyway) the wireless adapter, the sound device, Bluetooth are all missing. I can see (in the Hardware Drivers 'Additional drivers' tab) that nVidia drivers are loaded and that Broadcom drivers are loaded, but the sound and network status icons show red dots/indicators. The Broadcom drivers do have "(open source)" at the end of the name.
Why would a system update BREAK things which work after the original install? (Okay, dumb question...). WHAT is the update doing which is breaking drivers which work after the original install?
I'm new to running Linux on a Mac, and it may be something that's been dealt with many times over, so I apologise if I haven't managed to find the correct search terms.
Can anyone help with some tips on how to avoid system update packages trashing the working drivers?
