Here is the error I am getting when I try to update my system:

Hi!

Try this

sudo pacman -Sy archlinux-keyring manjaro-keyring
sudo pacman-key --populate archlinux manjaro
sudo pacman-key --refresh-keys

If doesnā€™t work, try this

Delete package cache
pacman -Sc
Delete as root
/etc/pacman.d/gnupg
Regenerate it with
sudo pacman-key --init
sudo pacman-key --populate archlinux

OK, the first did not work and after trying the second, here is what I get:

Also trying to install a file here is what I get:

Blockquote[terrym@SiriusTao ~]$ sudo pacman -F gimp
error: could not open file /var/lib/pacman/sync/core.files: Unrecognized archive format
error: could not open file /var/lib/pacman/sync/extra.files: Unrecognized archive format
error: could not open file /var/lib/pacman/sync/community.files: Unrecognized archive format
error: could not open file /var/lib/pacman/sync/multilib.files: Unrecognized archive format

Hi!
To install need to use -S not -F
Try to update with

sudo pacman-mirrors -f 3 && sudo pacman -Syyu
6

OK, so that worked for a bit until I got this error:

Try sudo pacman -Sc && sudo pacman -Syyu

I still get a missing key error and it will not update any file. They all download, but none will install due to the missing key. I have not installed anything other than packages from the official repositiories.

I also tried this:

sudo pacman-key --refresh-keys
gpg: refreshing 120 keys from hkps://hkps.pool.sks-keyservers.net:443
gpg: keyserver refresh failed: General error
==> ERROR: A specified local key could not be updated from a keyserver.

After about the twentieth try, it works. I just followed this

Pacman_troubleshooting
after your immense help @visone!

Hi!
Iā€™m just glad it work!!!

11

Adding keyserver hkp://pool.sks-keyservers.net to /etc/pacman.d/gnupg/gpg.conf did it for me.

12

I am having the same issue and already tried everything still i get:
sudo pacman -Syyu

I already did all of the helps (from old archived manjaro posts) but I have no Idea what is going wrong here. There is already something confusing when I do sudo pacman-key --populate archlinux manjaro:

then update keys
sudo pacman-key --refresh-keys

and back to the old errorā€¦

Update:

I found that when i delete /var/lib/pacman/sync and just use sudo pacman -Syyu then everything is fine. As soon as I open the Updated Pacman GUI and start an update here it will fail. Could this come from some AUR Packages?

Edit:
When I run Pamac update I get the Error again:

Deleting /var/lib/pacman/sync and running Pacman -Syyu fixed it but then I am not able to Update my AUR Packages anymore - is there anything known about that issue or is it temporary?

Somehow it is working again after some restarts and deleting the Databases. I think the connection to the Key-Server was disrupted and now itā€™s back againā€¦

worked for me. Thanks
