installation failed

[YuriFontella]

At the end of the installation this problem occurs.

I did the installation in UEFI with 2 partitions:

/dev/sda1
fat32
mount /boot/efi
flag boot

/dev/sda2
ext4
mount /

Package manager error
Package manager was unable to prepare updates. The command
pacman -Sy
returned error code 1

i faced the same problem when i tried it with cutefish reinstalling or recompiling may fix the issue, both worked for me
