Comment 3 Riccardo Schirone 2020-09-24 08:25:51 UTC 
WireGuard dissector was added in wireshark 3.0.0,  https://github.com/wireshark/wireshark/commit/f9c9af55278666ccc76e06e936bc243d82cb7317

This issue did not affect the versions of wireshark as shipped with Red Hat Enterprise Linux 5, 6, 7, and 8 as they did not include support for WireGuard.
