new installation: signature is invalid

I did a search for 'signature' in topic titles and didn't find the answer to this.
I installed the new 7.15 archlinux onto a SD card, and booted, reached this line from the instructions:

pacstrap /mnt base base-devel

signature from such and such is invalid.

i checked my date, and it is 2012 UTC Jul 28 09:26

I assume this shouldn't happen, but I don't why, or how to proceed from here. Any suggestions ? Thank you

Re: new installation: signature is invalid

There is no package "such and such".  Actual error messages are needed to troubleshoot problems.

Most importantly do you get this message once for one package?  If so, what is it?  Or do  you get this message dozens of times in a row with different packages in place of "such and such"?  The approach to these two situations would be very different.

In short, post the actual output you get from the pacstrap command.

Re: new installation: signature is invalid

i'll type it out:
pacstrap /mnt base
long list of targets (acl, archlinux-keyring, etc)
total installed size 410.52 MiB

proceed with installation (y/n)
(114/114) checking package integrity
error: getteext: signature from "Tobias Powalowski <tobias.powalowski@googlemail.com>" is invalid
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded
==> ERROR: failed to install packages to new root

I downloaded the .iso and the md5 was correct
I guess the packages were downloaded but for some reason the signature was invalid

, thanks for help

Re: new installation: signature is invalid

OK, I just tried it again, and almost the same result.
To be clear, i downloaded the .iso (7/15), checked the md5, installed it to a SD card.
I booted with the card,  did 'dhcpcd' to get network, erased the hard drive by creating a new partition, then i went ahead with the installation instructions. 

# pacstrap /mnt base
so it goes through and downloads all the packages but then:
114/114 checking package integrity
error: linux: signature from "Tobias Powalowski..." is invalid

the instructions said to check the date, but it seems to be correct, so i don't know how to fix this problem.

@thideras: This is not needed on the install media.

Re: new installation: signature is invalid

I ran into this today during my first attempt at installing arch, and it did end up being because my date was set incorrectly. Even after I corrected the time, I still couldn't get the command to work correctly until I started the install over. I'm guessing when I initially ran pacstrap it downloaded some files that ended up getting marked with the wrong date and I couldn't figure out how to force them to redownload. So my suggestion would be to run 'ntpd -qg' (you should get a message that it succeeded), followed by 'hwclock -w' and then try reinstalling. Hope that helps!

Re: new installation: signature is invalid

Ah, after poking around a little more, I wonder if following these directions to remove stale packages after the time has been fixed would fix the issue. It would be nice if somebody could test that out, and then update the wiki if it works.
