You are facing

Easiest workaround is to remove skype, remove skype repo, and install it as flatpak from flathub

Skype have issued a new GPG key:

sudo rpm --import https://repo.skype.com/data/SKYPE-GPG-KEY

I had to go further.
I deleted the skype repo
rm /etc/yum.repos.d/skype-stable.repo
then got the skype key
rpm -qa gpg-pubkey --qf "gpg-pubkey-%{version}-%{release} %{summary}\n"
which was
and removed it
rpm -e gpg-pubkey-df7587c3-576a5c23
and then added the repo again
curl -o /etc/yum.repos.d/skype-stable.repo https://repo.skype.com/rpm/stable/skype-stable.repo
and finally updated skype, which now prompts me to accept the key again and finished successfully
dnf clean all; dnf update skypeforlinux


@uriesk 's method worked for me as well, except there was no need to delete the skype repo and re-add it. Just removing the old gpg key and re-running update was sufficient:

rpm -e gpg-pubkey-df7587c3-576a5c23
dnf update skypeforlinux

Thanks, it works.

Thanks, it works.

And rpm -qa gpg-pubkey reminds me that I need to clean many old gpg pubkeys, starting from Fedora 19.
