First of all, I’m sort of a linux noob (I only have a little bit of experience), but anyways, here’s my problem:
Yesterday I made a bootable USB stick with antergos and tried installing it. cnchi got stuck after something like “Getting list of packages to install”. That seems to be gone now, but when I tried it today, I got the error mentioned in the title.
Here are the logs: 0_1453911061308_cnchi.log.tar

If it matters, I ran it again and that error appeared immediately after installing the packages.
