Key xxxxx could not ne looked up remotely

Bad new I’m afraid.
There were many messages like this:

:: File /var/cache/pacman/pkg/librewolf-extension-plasma-integration-1.8.1-2-any.pkg.tar.zst is corrupted (invalid or
corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
error: minecraft-launcher: signature from "Nico Jensch (Chaotic-AUR) <[email protected]>" is invalid
:: File /var/cache/pacman/pkg/minecraft-launcher-928-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (
PGP signature)).
Do you want to delete it? [Y/n]

So i answer Yes to each one but ultimately it failed with this unhelpful message (no package name):

error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.

Thanks for helping me with this. I’ll post

the entire log

if you can point me to say how you want it. Don’t think you want cut 'n paste do you?
