Hi!
For some background to my question, I run two laptops with Manjaro, which I routinely update using sudo pacman -Syu
. Two weeks ago, I did what I thought was a normal update on one of them (it didn’t seem as though my internet went down or anything), but when I tried to reboot it was broken. I followed all the regular advice to go in with a USB and reinstall grub via chroot but could not get it working and ended up just recovering my files and reinstalling the whole OS.
Now, I’m trying to be much more careful about updates and really pay attention to the console output & learn the intricacies of the process in better detail. So I’m on the other laptop, and just got this warning during an update:

I have not rebooted yet. I am not super bootloader savvy yet and I’d really appreciate some help understanding & interpreting this, whether I need to reinstall grub or not, and if it is safe to reboot. Please let me know if there’s any other info/output I can provide to help! Thank you!
