Can't update pacman.

I have a strange problem. I haven't updated Arch since sometimes in January, and today when I tried to it asked me to update pacman first. I said yes, and got this:

sudo pacman -Syu
Password: 
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
 repo-ck is up to date
:: The following packages should be upgraded first :
    pacman
:: Do you want to cancel the current operation
:: and upgrade these packages now? [Y/n] y

resolving dependencies...
looking for inter-conflicts...
error: failed to prepare transaction (could not satisfy dependencies)
:: pyalpm: requires pacman<3.6

What do I do now?

EDIT:

pacman -Qi pacman

Re: Can't update pacman.

pacman -S pacman pyalpm

should work

Running arch is like raising a puppy - if you spend a bit of time with it each day and do just a bit of training you'll end up with the most loyal partner you could want; if you lock it in a room and don't check on if for several days, it'll tear apart your stuff and poop everywhere.

Shouldn't he remove pyalpm, update pacman, then reinstall pyalpm?

It's a known bug, manually and explicitly updating pyalpm solves the problem. Doesn't mean your solution wouldn't work

Re: Can't update pacman.

Rerun the command, but say no.

It will still update pacman, it just will not do it *first* which is what is causing the problem.

Responding NO will allow the full update to proceed, then make sure to merge your pacnew's and check the wiki to set up package signing.

Re: Can't update pacman.

I have encountered this case for several times, I usually remove other packages and update pacman first, then install the packages again.
