@Steveg58 @Natanox @canadaduane hum, weird, 3.0.20 package is un stores ( on debian for exemple) https://packages.debian.org/buster/amd64/vlc/download
Is it a require dependence missing ?
If you still want the lastest without trying to find this error somewhere 'apt remove VLC && snap installé vlc'
(On install the debian .deb )
