I use the Fedora rpm package of the meetings desktop client However, I only want to install software that is correctly cryptographically signed. That was not a problem so far. However, the recent version 5.8.4 (210) is not signed at all (see rpm -qpi output below), and the gpg signature validation fails.
$ rpm -qpi zoom_x86_64.rpm

Hey @jknaus, here is some insight I got on a similar case to yours; however, I'd advise to first update to the latest version 5.8.6 to see if this helps! If not, here is a suggestion that may help!
On Download Center https://zoom.us/download if you select Linux Type: Fedora, under the Download button there is the following text: "Zoom's rpm packages are signed with a GPG key. Please run "rpm --import package-signing-key.pub" to import the key in case package management utility asks for a missing public key."
You can try running the command and see if the new version of the package is signed again.
