Arch broken system due to power loss during update

[indigo spindle]

I have broken my system by running an update while power went out. My boot manager only shows the option to boot into firmware, not into linux. If I chroot into the system, I am unable to run mkinitcpio -P as I get the error "no presets found in /etc/mkinitcpio.p" because I removed the empty linux.preset file in there. I did so because that was a recommendation from an old forum comment. The same comment recommended to the run pacman -S linux, which gives errors in the form of linux: _____ exists in filesystem

[indigo spindle]

also my mstab file is missing

Run the same basic installation steps except anything that may cause data loss, ie formatting and partitioning, disk dupe(dd), just go with the basics such as mounting, lsblk, filesystem integrity checks, pacstrap and firmware installation, recovery of anything you may have lost or corrupted

[bold peak]

By this are you referring to fstab or mtab?

[indigo spindle]

mtab, my bad

[bold peak]

Can you show the error?

[indigo spindle]

oops, it wasn't there when I accidentally used chroot, but it is there when I use arch-chroot

anyways, the wiki tells me to arch-chroot into the systemd and use pacman -S ___ for every package that was updated, but there's too many to type in and I don't think it'll work anyways because if I do individual packages I get the same errors as in my first message

[bold peak]

So don't install linux

[indigo spindle]

what should I do instead then?

[bold peak]

Is it a fresh install

[indigo spindle]

no it's not

also, running pacman --root=/mnt --cachedir=/mnt/var/cache/pacman/pkg -Syu before arch-chroot seems promising but it complains about the semver key having unknown trust

[bold peak]

Hm

@sleek jay sorry to ping you but do you have any ideas regarding this?

[indigo spindle]

I ran # pacman -Qqn | pacman --overwrite "*" -S - and now have a half working system

sudo pacman -Qkk tells me about a lot of packages that have something wrong

[bold peak]

Try -Qtdq to check for any orphans and get rid of them

[sleek jay]

don't ever do that
