Arch doesn't boot after update.

Arch is stuck at Starting version 245 after running pacman -Syu

And what have you done to try to get past this?

Can you switch TTYs (Alt+F3)? Have you tried alternative boot targets on the kernel line? Do you have a live medium to boot into to gather logs? If not, can you make one?

Without any information there is absolutely nothing anyone could do to help.

No i can't switch TTYs and i haven't tried alternative boot targets. I have a live medium to boot into.

So try some? And/or use it and get some information? What else is anybody supposed to say?

hello i faced the same problem too i solved it today:
boot into arch live usb then :
mount root drive for me :

$ mount /dev/sda7 /mnt

then mount home drive if you have for me:

$ mount dev/sda6 /mnt/home

then run:

$ pacman -Syyu

after that:

$ mkinitcpio -p linux

then reboot, i hop that helps you.

Certainly not, because that's a completely broken recap of https://wiki.archlinux.org/index.php/Pa … an_upgrade

thanks it worked!

I hope/suspect that you do not have a boot partition. If you do you just pushed the breakage somewhere else. But really I don't care - you refuse to provide any information when prompted, so I refuse to help with your future problems.

Mark your thread as [SOLVED].

thekiller2, share your pacman.log.

If he did exactly as post #5 said, he won't have done anything anyway.
Leaving aside the pointless and probably failing /home mount, the possibly missing /boot mount and the random device nodes used: w/o a chroot he operated on the live media this way - not on the installed one.

what you talking about, are you akay??

i told you i solved my problem, and the person who asked the question too.

I'm telling you that your description lacks some severely relevant calls and if it worked despite, your system works by voodoo magics.
What you posted *cannot* what - no matter what you believe.

You know I had a really bad cold once. A friend had a sure fire cure: she said every morning for 1 week, stand on one foot with one hand on your head and the other covering your eyes for 2 minutes. I followed this regime for 1 full week, and I was amazed: my cold was gone!

That ritual is precisely as effective at curing the common cold as the steps in post #5 would be at fixing any problem in an arch linux system. I don't think anyone doubts that you had a problem before you did those steps, nor that the problem was gone after those steps. It is, however, absurd to think that those steps had anything to do with the problem going away. But everyone is allowed their superstitions.

go and see a doctor we don't cure cold here

You just made my morning coffee worthwhile.

I too suffered from this issue. I used a live usb to get the pacman.log but its content is useless. Looking at the post on how to deal with pacman crashes, it simply looked like the initramfs image was broken, what I did to fix the installation was:

1. mount the system sda at /mnt
2. arch-root /mnt
3. mkinitcpio -p linux
4. exit and unmount everything
5. reboot

I still do not know what exactly went wrong with the update, but the bottom line is updating the kernel broke the initramfs.

Since FAT is a pretty bad file system for stability and integrity, what with no journaling and all, there can be all sorts of fun reasons for why your initramfs might be corrupted. One that is pretty easy to happen is having e.g. an unclean shutdown (this one happens often at my university that the network shares might hang and delay the shutdown, if you have to be somewhere and you don't want to stare at the timeout screen but decide to forcefully bring it down, you better hope your FAT has been synced in the meantime) Best option to have some guarantees here is to add a pacman post transaction hook that runs sync on /boot as the last hook to be ran. Afaik there's an example for that in

man alpm-hooks

I am going to grind this mangle to a halt as the OP and another have declared this as having been resolved. Closing.
