Problem installing Ubuntu Server 21.04 on Macmini5,2

**rbrdvr** · April 25th, 2021

I tried installing Ubuntu Server 21.04 on Macmini5,2. No problem booting the USB or during installation process but the machine freezes when when trying to boot from its EFI, right away, before grub menu, so no diagnostics. I tried using all defaults as far as partitions or file systems go.

I don’t think it’s related to 32bit vs 64bit EFI since this version of mini is supposed to have 64bit, according to https://everymac.com/systems/apple/m...011-specs.html . But if anyone have any ideas on how to test it, please let me know, I’m a newbie.

The contents of EFI partition looks ok, with all usual files and directories present.

Same problem with Kubuntu 21.04.
Fedora 34 beta boots fine as well as no problem with Ubuntu 18.04 (bodhi 5.x distro).

Yes I have the same problem on both my MacBook and iMac. 21.04 will not boot left with frozen blank screen. Had to revert to 20.10 on both machines.
Desktop edition not server!
