[SOLVED] arch failed to boot after system upgrade

[SOLVED ]I run a full system upgrade today and after a reboot arch failed to mount /boot

I used a live ISO to boot and mount all partitions, then arch-chroot and run a `journalctl -xb -p 3`

The kernel parameters include `systemd.zram=0` and `zswap.enabled=0`

While in chroot I've run a `pacman -Syu linux linux-lts` but didn't help.
Anyone knows how to debug this?

Re: [SOLVED] arch failed to boot after system upgrade

I am having the same issue on EndeavourOS.  Updated to 6.6.5 and get failed to mount /efi and all the snap targets.

Digging some more, I noticed that my bootloader says 6.6.2.  I tried downgrading to kernel 6.6.2 and rebooted, and was able to get my system running again.

Re: [SOLVED] arch failed to boot after system upgrade

journalctl -xb -p 3

that's useless and spam

journalctl -b | curl -F 'file=@-' 0x0.st

as well as the failure to mount a vfat partition yells that you're booting an older kernel, either because you forgot to mount the /boot partition or because you mounted one, but are actually not booting from there.
Journal will tell.

Re: [SOLVED] arch failed to boot after system upgrade

Okay I looked more closely through the journal and found

Unknown filesystem type vfat

In the live ISO I mounted the boot partition to /mnt/boot and root to /mnt and run another `pacman -Sy linux linux-lts`, rebooted and now everthing works. I don't know why as I'm certain I've run the same thing yesterday already and it didn't work afterwards...

you're booting an older kernel, either because you forgot to mount the /boot partition or because you mounted one, but are actually not booting from there

pacman -Sy linux linux-lts

Or your're habitually running partial updates, make sure to "pacman -Syu", otherwise the next "pacman -S foo" might get you into trouble.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
