paru/yay "No name" when updating packages

If paru/yay outputs something like:

:: Proceed with installation? [Y/n]: y
:: keys need to be imported:)

First make sure ~/.gnupg/gpg.conf has a valid keyserver like:

keyserver hkps://keys.openpgp.org:443

Also make sure that /etc/pacman.d/gnupg/gpg.conf has a valid keyserver.
f.ex:

keyserver hkps://keys.openpgp.org:443

and the keyserver is actually available.

For me this file initially had hkp://pool.sks-keyservers.net or hkp://keyserver.kjsl.com:80 which are now deprecated and no longer operating.

Available keyservers: * hkps://keys.openpgp.org:443 * hkp://keyserver.ubuntu.com:80
