- Why is the Lubuntu install not working? How can I make it work?
- Why are my Windows partitions not showing up in any partition managers?
Confused? Read below.
What I Did
- I have an old MacBook air lying around that I had installed Arch Linux on.
- I kinda got tired of Arch Linux, and wanted to see the effects, so I did the classic
rm -rf / --no-preserve-root.
- Yesterday, I wanted to install Lubuntu. I flashed it to a usb flash drive with Etcher.
- I launched the installer and ran it, choosing to erase disk and install Lubuntu.
- It was a success, until the end where I got the error
grub-efi-amd64-signed failed installation /target/. Looking at the logs, I also got the errors
ubiquity: E: Unable to locate package shim-signedand
grub-installer: info: calling 'apt-install grub-efi-amd64-signed' failedand the installer crashed.
- Thinking it might be a lack of internet connectivity, I connected to ethernet. I know it worked because the option to download updates wasn't greyed out. It still didn't work.
- I read somewhere that I might need a EFI system partition, so I manually partitioned it. It still didn't work.
- Getting tired of that, I wanted to have some operating system, so I created a bootable Windows 10 installation media with Rufus. It installed perfectly, and Windows worked fine after I installed the BootCamp support drivers, besides no bluetooth or multitouch trackpad support.
- Again, I wanted to install Lubuntu, maybe install it to another hard drive (an HGST Touro S). So I opened up the Lubuntu installer again and manually partitioned my hard drive (the external one). Of course, it failed...
- BUT I noticed a weird thing. The partition manager in the Lubuntu installer said that my MacBook's hard drive was empty. 100% free space. The same thing appeared on GParted in the Lubuntu live OS.
- But that's weird because my computer boots, and on the Windows Disk Management app it says that there are partitions.
I am re-posting a question from superuser that is now deleted. This was recommended here.
