Can you give the precise error message? Some of the packages (e.g.) filesystem need to be installed with --force, because they overwrite files that were previously automatically generated etc. See the news on the main website for more details. On Mon, 18 Jun 2012, D. R. Evans wrote:
I am getting a failure when attempting to install 64-bit arch as the main OS on my principal desktop system.
I am following the instructions at https://wiki.archlinux.org/index.php/Software_RAID_and_LVM, since I have two brand-new 2TB drives that I want to use in RAID1.
1. I have downloaded and burned the current NetInstall image on a CD. 2. Booting from the CD, I execute: /arch/setup 3. I execute: modprobe raid1 4. I execute: modprobe dm-mod 5. I execute: pacman-db-upgrade 6. I execute: pacman -Syy
All the above works fine.
7. I execute: pacman -S gdisk
At this point I am told that I should upgrade pacman, and am asked if I want to do this. I answer "Y". A bunch of stuff gets download, but eventually I am told that the upgrade cannot be performed.
Possibly this is because it's attempting to write to a read-only filesystem -- i.e., the CD drive (I'm guessing wildly that that is the cause). But in any case, I can't get past this point.
How do I proceed?
