When doing an apt-get update/upgrade I see that error
W: Conflicting distribution: https://downloads.plex.tv/repo/deb public InRelease (expected public but got )
I was upgrading to Ubuntu Zesty 17.04 before and do not know how to fix the above. Already have seen https://forums.plex.tv/discussion/162337/plex-media-server-ppa-for-ubuntu/p4? but there are no suggested fixes for that.
Maybe one of you can give some hints? Thanks!
Edit
/etc/apt/sources.list.d/plexmediaserver.list
And replace
deb https://downloads.plex.tv/repo/deb/ public main
with
deb https://downloads.plex.tv/repo/deb/ ./public main
...that worked for me.
