I have three raspberry Pi3, Stretch, OMSC 18.2 July version.
All three have exact same behavior, since more than a week:
They destect an update, try to download, and fail.
With SSH I do
sudo apt-get update && sudo apt-get dist-upgrade
Then I have this error :
Get:1 http://security.debian.org stretch/updates InRelease [94.3 kB]
Hit:2 http://ftp.fau.de/osmc/osmc/apt stretch InRelease
Err:3 http://ftp.debian.org/debian stretch InRelease
Could not connect to klecker-ftp.debian.org:80 (184.108.40.206), connection timed out Could not connect to ftp.acc.umu.se:80 (220.127.116.11), connection timed out Unable to connect to ftp.debian.org:http: [IP: 18.104.22.168 80]
Err:4 http://ftp.debian.org/debian stretch-updates InRelease
Unable to connect to ftp.debian.org:http: [IP: 22.214.171.124 80]
sources.list seems ok :
deb http://ftp.debian.org/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
They all are connected with RJ45, have internet, and all local libraries on network (NAS) works like usual.
No addons, just movies and music in a local db.
Is there something I can check ?
