Trying to install “Ubuntu Base” in Vmware but getting a kernel panic!

Here is how I install Ubuntu Base in Vmware:

Quote:

load the live media
sudo passwd root
su root

parted -a optimal /dev/sda

* mklabel gpt
* print
* remove remaining partitions.(if there are any).
* unit mib
* mkpart primary 1 512
* name 1 boot
* set 1 boot on
* mkpart primary 512 -1
* name 2 rootfs
* print
* quit

mkfs.fat -F 32 /dev/sda1
mkfs.ext4 /dev/sda2

mount /dev/sda2 /mnt

tar xvfz ubuntu-base-20.04.1-base-amd64.tar.gz -C /mnt

cp /etc/resolv.conf /mnt/etc/resolv.conf

mount --rbind /sys /mnt/sys
mount --rbind /proc /mnt/proc
mount --rbind /dev /mnt/dev

chroot /mnt
mount /dev/sda1 /boot

apt-get update
apt-get install --no-install-recommends grub-efi
apt-get install --no-install-recommends linux-image-5.4.0-48-generic
apt-get install --no-install-recommends initramfs-tools
apt-get install --no-install-recommends nano

nano -w /etc/default/grub
update-grub
grub-install --target=x86_64-efi --efi-directory=/boot

nano -w /etc/fstab
----
/dev/sda1 /boot vfat defaults,noatime 0 2
/dev/sda2 / ext4 noatime 0 1
----

adduser l3gi0n
addgroup l3gi0n adm
addgroup l3gi0n sudo

passwd root

exit

reboot

I am getting this Kernel Panic: https://ibb.co/XFTKBtN

What did I do wrong ?

Reconfigure initramfs. The efi partition on /boot maybe the problem as fat32 doesn't support symlinks. On ubuntu systems the efi partition is usually mounted at /boot/efi and the boot partition if one exist mounted at /boot and normally formatted ext4. Any errors when running the apt-get commands? Does /usr/sbin/init exist?

I get this error during the kernel's installation(through apt) : https://ibb.co/PDJtFVF

Is this error why I get the kernel panic ? Can you tell me exactly what to do to get rid of this error ?

Instead of mount /dev/sda1 /boot I should do:

Quote:

mount /dev/sda1 /boot/efi

Instead of grub-install --target=x86_64-efi --efi-directory=/boot I should do:

Quote:

grub-install --target=x86_64-efi --efi-directory=/boot/efi

and my /etc/fstab line should read:

Quote:

/dev/sda1 /boot/efi vfat defaults,noatime 0 2
/dev/sda2 / ext4 noatime 0 1

On my Kubuntu laptop, /dev/sda1 is formatted as fat32...

Many Thanks

The efi partition should be formatted fat32, on your system is /dev/sda1

I already partitioned it as fat32:

mkfs.fat -F 32 /dev/sda1

Resolved the issue by editing /etc/kernel-img.conf and adding:

Quote:

do_symlinks = no
no_symlinks = yes

You will have less issues if you run the apt-get install commands in reverse order and add

Code:

apt-get install --no-install-recommends init

to the list
