error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.
The list looks so big as I haven’t been able to update my system for a long time.
As mitigation, I’ve tried updating archlinux-keyring and endeavouros-keyring packages but to no avail.
Thanks for the help.
