Arch update failed because of signature unknown trust
I was trying to update Arch and it failed and said:
error: onetbb: signature from "Torsten Keßler <tpkessler@archlinux.org>" is unknown trust
I looked for several solutions that didn’t work already. I’m not sure how to fix something like this so any help is appreciated.
You can try to reinstall the key using sudo pacman -S archlinux-keyring
After reinstalling it you can try to refresh the key using sudo pacman-key --refresh-keys.
If above solutions don’t work you can manually trust the key with the following command:
sudo pacman-key --lsign-key tpkessler@archlinux.org
