[SOLVED] Pacman is unable to look up keys?

Hi there,

I'm using Arch Linux for a while, and I'm using pacman 4.0 as well as key signing. It works without any problems, and I run system upgrades every 3 days or so.

Today i just want to initiate the upgrade with "pacman -Syu" as usual, but pacman refuses it because it is unable to check the keys. Since it did work perfectly before, I - of course - did pacman key initialization and configured the pacman.conf properly.

My pacman.conf looks like this (important parts)

# PGP signature checking
# NOTE: None of this will work without running `pacman-key --init` first.
# The compiled in default is equivalent to the following line. This requires
# you to locally sign and trust packager keys using `pacman-key` for them to be
# considered valid.
#SigLevel = Optional TrustedOnly
# If you wish to check signatures but avoid local sign and trust issues, use
# the following line. This will treat any key imported into pacman's keyring as
# trusted.
SigLevel = Optional TrustAll
# For now, off by default unless you read the above.
#SigLevel = Never

[core]
SigLevel = PackageRequired
Include = /etc/pacman.d/mirrorlist

[extra]
SigLevel = PackageOptional
Include = /etc/pacman.d/mirrorlist

[community]
SigLevel = PackageOptional
Include = /etc/pacman.d/mirrorlist

gpg.conf

no-greeting
no-permission-warning
lock-never
keyserver hkp://keys.gnupg.net
keyserver-options timeout=10

I also tried increasing the timeout and changing the keyserver to hkp://pgp.mit.edu:11371, as adviced in other threads, but no help.

Cleaning the caches with pacman -Sc didn't help ether. I also restarted the system several times, but no success.

Any help? Thanks!

Cleaning the cache with pacman -Sc will leave the most recent downloaded version there, so delete the package manually from the cache and run pacman -Syu again.
