Manjaro won't boot up after update

Hi @MHT130, and welcome!

I’m going to tell you that if you don’t know what to do in this situation, you shouldn’t use the unstable branch, as that’s, well, unstable and could lead to breakages.

That said, I recommend you chroot into your system, change to the stable branch, and resync your system.

How to chroot

  1. Ensure you’ve got a relatively new ISO or at least one with a still supported LTS kernel.

  2. Write/copy/dd the ISO to a USB thumb drive.

  3. When done, boot with the above mentioned USB thumb drive into the live environment.

  4. Once booted, open a terminal and enter the following command to enter the chroot encironment:

manjaro-chroot -a
  1. If you have more than one Linux installation, select the correct one to use from the list provided.

When done, you should now be in the chroot environment.

But, be careful, as you’re now in an actual root environment on your computer, so any changes you make will persist after a restart.

If successful, change to the stable branch by running:

sudo pacman-mirrors --api --set-branch stable

Followed by updating your mirror list and syncing your system:

sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu

Hope this helps!
