Hi,
I’m not sure what you mean by that. Even then, when I replace the sources.list by the clean version from here: Osmc update doesn't works - solved! - #9 by ActionA, the system seems up to date:
osmc@osmc:~$ cat /etc/apt/sources.list
deb Index of /debian stretch main contrib non-free
deb Index of /debian stretch-updates main contrib non-free
deb http://security.debian.org/ stretch/updates main contrib non-free
deb http://apt.osmc.tv stretch main
osmc@osmc:~$ sudo apt-get update
Hit:1 http://security.debian.org stretch/updates InRelease
Ign:2 Index of /debian stretch InRelease
Hit:3 Index of /debian stretch-updates InRelease
Hit:5 Index of /debian stretch Release
Hit:4 Index of /osmc/osmc/apt stretch InRelease
