"Failed to mount /boot/efi" after 2026-06-26 stable update

CHROOTING:

[manjaro ~]# chroot /mnt /bin/bash
[manjaro /]#

For live image system recovery type tasks, you should be using manjaro-chroot, not the regular chroot.

One of the things I loved about Manjaro is I didn’t have to do this the old convoluted Arch Linux way, I just shorten all of this:

MOUNTING PARTITIONS:

sudo su -                                                                                                                            ✔ 
[manjaro ~]# cryptsetup luksOpen /dev/nvme0n1p2 cryptroot
[manjaro ~]# mount /dev/mapper/cryptroot /mnt
[manjaro ~]# mount /dev/nvme0n1p1 /mnt/boot/efi

BINDS AND MOUNTS:

[manjaro ~]# mount --bind /dev /mnt/dev
[manjaro ~]# mount --bind /dev/pts /mnt/dev/pts
[manjaro ~]# mount -t proc proc /mnt/proc
[manjaro ~]# mount -t sysfs sysfs /mnt/sys
[manjaro ~]# mount -t efivarfs efivarfs /mnt/sys/firmware/efi/efivars
[manjaro ~]# mount --bind /run /mnt/run

CHROOTING:

[manjaro ~]# chroot /mnt /bin/bash
[manjaro /]#

To this:

sudo cryptsetup luksOpen /dev/nvme0n1p2 cryptroot
sudo mount /dev/mapper/cryptroot /mnt
sudo manjaro-chroot /mnt /bin/bash
mount /boot/efi

Then try to install your kernel.

(And exit chroot and reboot.)

umount /boot/efi
exit
reboot
