Installing mbp-ubuntu on Macmini8,1

[jrjsmrtn]

Following your procedure, I tested the mbp-ubuntu v20.04-5.7.19-1 ISO on a Macmini8,1.

I found three issues:

1. Grub is failing with failure reading sector 0x*** from 'cd*' and no such device: *** errors and land in its shell. Executing chainloader /efi/ubuntu/grubx64.efi & boot brought me a step further.

2. the boot either pauses or completely freezes after those two messages:

   1. bce-vhci: Not implemented: wait for pending output requests

   2. brcmfmac: brcmf_fw_allow_request: using brcm/brcmfmac4364-pcie for chip BCM4364/3

3. past those steps, the HDMI display goes nuts. The host doesn't appear in my DHCP server, so I suppose it's not just a display issue.

My complete log follows. Hope this helps...

1. Added 2 partitions with diskutil: a 32GB for swap and a 250GB for Linux root 
(I didn’t add a /boot partition — maybe I should ?)

   $ sudo diskutil list
   /dev/disk0 (internal, physical):

2. Successfully rebooted with a mbp-ubuntu v20.04-5.7.19-1 Live USB, without Thunderbolt.

3. Successfully installed on 250GB ext4 Linux partition.

4. Rebooted and selected « EFI Boot » in boot manager.

5. Got this:

Hi, did you discuss this issue in the discord channel? There you will find possibly somebody that already install it on the same device.
