Hi.

On Arch 64-bit, up to date (as of about 12 hours ago), I just did:

sudo pacmatic -Syyuv

Here's the result:

Root : / Conf File : /etc/pacman.conf DB Path : /var/lib/pacman/ Cache Dirs: /var/cache/pacman/pkg/ Hook Dirs : /usr/share/libalpm/hooks/ /etc/pacman.d/hooks/ Lock File : /var/lib/pacman/db.lck Log File : /var/log/pacman.log GPG Dir : /etc/pacman.d/gnupg/ Targets : None :: Synchronizing package databases... core 120.8 KiB 417K/s 00:00 [##################################] 100% extra 1750.7 KiB 2.88M/s 00:01 [##################################] 100% community 3.4 MiB 3.59M/s 00:01 [##################################] 100% :: Starting full system upgrade... resolving dependencies... looking for conflicting packages...

Tried pacman -Syyuv. Same result.

Rebooted. Same result.

Did sudo reflector --verbose --country 'United States' -l 200 -p https --sort rate --save /etc/pacman.d/mirrorlist, then pacman -Syyuv. Same result.

So, this seems to be the relevant section:

error: failed to commit transaction (conflicting files) util-linux: /usr/share/bash-completion/completions/mount exists in filesystem util-linux: /usr/share/bash-completion/completions/umount exists in filesystem Errors occurred, no packages were upgraded.

Any idea what the problem might be?
