Signature is unknown trust [SOLVED]

I seem to be having the same problem as this topic but the solution offered did not work for me. The problem and solution is also described here.

I'm trying to install i3 but get this error:

:: Proceed with installation? [Y/n] error: i3-wm: signature from "Thorsten Töpper <atsutane@freethoughts.de>" is unknown trust
:: File /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] error: failed to commit transaction (invalid or corrupted package (PGP signature))

I've tried cleaning out the cache with "pacman -Sc && rm /var/lib/pacman/sync/*", refreshing signatures with "pacman-key --refresh-keys" and reinstalling, but that did not work.

I also tried resetting all the keys and upgrading archlinux-keyring per the wiki to no avail.

Re: Signature is unknown trust [SOLVED]

Try the following commands and see If you get the same results

ewaller@turing ~ 1004 %ls -l /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz 
-rw-r--r-- 1 root root 253152 Oct 13 11:10 /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz
ewaller@turing ~ 1005 %md5sum /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz 
7d8408a9222dcaeff6e059b53ab4028a  /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz
ewaller@turing ~ 1006 %

Edit:  Fixed first command because I had used ll as an alias for ls -l

Good to know I am not alone with this abbreviation.

$ls -l /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz
-rw-r--r-- 1 root root 253152 Oct 13 18:10 /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz
$md5sum /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz
7d8408a9222dcaeff6e059b53ab4028a  /var/cache/pacman/pkg/i3-wm-4.11-1-x86_64.pkg.tar.xz

It looks the same except for the date from ll

Re: Signature is unknown trust [SOLVED]

Okay, the package is not corrupt.

I just tried looking at his key on my system and it expired yesterday.

ewaller@turing ~ [2]1003 %gpg --list-key Thorsten
pub   dsa2048/295AFBF4 2009-02-20 [expired: 2016-01-22]

Check that on your system

Re: Signature is unknown trust [SOLVED]

... And I just did a gpg --refresh-keys and he has a new key that expires 2017-09-08

If his key on your system is stale, do a refresh keys and try again.

Re: Signature is unknown trust [SOLVED]

list-key gives me:
gpg: error reading key: No public key

refresh-keys and trying again gave the same result

I have this same issue as well. refreshing the keys does not do anything

Re: Signature is unknown trust [SOLVED]

I have been away all day.  I think that a pacman -Syu  from a fully synced mirror should solve this.  I see the Arch keyring has been updated today.

Pacman has his own keyring by default.

sudo pacman-key -l Thorsten
pub   dsa2048/295AFBF4 2009-02-20 [verfallen: 2016-01-22]
uid      [  verfallen] Thorsten Töpper <atsutane@freethoughts.de>
uid      [  verfallen] Thorsten Töpper <t.toepper@gmx.de>
uid      [  verfallen] Thorsten Toepper (Atsutane) <atsutane@freethoughts.de>

sudo pacman-key --refresh-keys

This fixed it for me.

Re: Signature is unknown trust [SOLVED]

All is well. pacman -Syu && pacman-key --refresh-keys got it done this time.

To make sure I understand what happened:
Thorsten recently got a new key pair and updated his private key on the package but did not publish his public key. This caused my earlier attempts at installation and refreshing keys to fail. Today his public key was updated, allowing the installation to proceed smoothly. Is this correct?

Re: Signature is unknown trust [SOLVED]

Pretty much.  I think the magic happened when arch-keyring was upgraded and had time to propagate to the servers. 
I started with checking the package itself as that is the purpose of this whole infrastructure.  I'd have hated to try to chase down cryptography problems only to find out that things were working as they were supposed to.

Re: Signature is unknown trust [SOLVED]

The new archlinux-keyring package is still lingering in testing, having fun there I guess.
So it doesn't do a lot of good (yet) to the majority of people who don't enable testing.

`pacman-key --refresh-keys`, on the other hand, works perfectly, right now, since the maintainer's new key has been pushed to the public keyservers.
