After installing RPM Fusion repos on Fedora 28 you might be getting an error shown by update manager every few minutes in GUI.

Chromium supports Vorbis, Theora, WebM and HTML5 audio and video standards, but does not include the non-free AAC, H.264, MP3 or Adobe Flash code that is found in Chrome.

Workaround
Issue can be resolved by running export NSS_DISABLE_HW_AES=1, and then running yum update, to update to newer packages, after which issue should not be happening anymore.
