GPG error updating to Fedora 42

Hello,
I have a fedora 40 and I would like to update to 42. I ran:

sudo dnf upgrade --refresh
sudo dnf system-upgrade download --releasever=42

But I got the error:

...

GPG key at https://d2t3ff60b2tol4.cloudfront.net/repomd.xml.key (0xACCAF35C) is already installed
The GPG keys listed for the "insync repo" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.. Failing package is: insync-3.9.6.60027-fc42.x86_64
 GPG Keys are configured as: https://d2t3ff60b2tol4.cloudfront.net/repomd.xml.key

Try to add '--enableplugin=expired-pgp-keys' to resolve the problem. Note: This plugin might not be installed by default, as it is part of the 'dnf-plugins-core' package.

The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.
Error: GPG check FAILED

No update was complete so I am still with 40.
How can I solve this error?
Thank you
