Just did the updates, rebooted and was presented with a command prompt after a error message. I could not type anything into the prompt so hard rebooted, presented with same error and unusable prompt, hard rebooted, selected advance and the 5.7 kernel, was presented with the same error and a useless prompt again., another hard reboot, advanced, kernel 5.6, and booted into my desktop. Just received another 500+ megs of updates, once done will reboot and try the 5.8 kernel again. If I get the same message will edit this post and add it here.
OK with attempting the 5.8rc7 I get "[FAILED] Failed to start Load Kernel Modules.", attempting with the 5.7.11 I get that and a list of my drives / partitions that timed out attempting to load / mount.
