No Internet with OSMC but with Jessie Lite yes

Hi folks,

since 5 days I do not get any more internet connect via my Pi 2 B and OSMC.
LAN/SSH etc. still worked fine and without any issues.
Regardless whether trying to get online from an OSMC app like YouTube or via SSH (apt-get update), both doesn’t work.

Today I tried a fresh install at the same Pi using Jessie Lite, and guess what it can now connect to the internet.

When I switched the Pi on 2 days ago OSMC told me that the last automatic update failed.
So after that I restored an old OSMC image from February which was definitely error-free back to the flash card, but that also didn’t help.

Here comes an output from the console when trying to download the update:
~$ sudo apt-get update ... Err http://apt.osmc.tv jessie Release.gpg Could not resolve 'apt.osmc.tv' ... W: Failed to fetch http://ftp.debian.org/debian/dists/jessie/InRelease ... W: Some index files failed to download. They have been ignored, or old ones used instead.

Since with Jessie Lite I am able to connect to the internet, I thought to install OSMC afterwards, however there I got stuck with installing OSMC:
~ $ sudo apt-get install osmc-installer Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package osmc-installer

Any ideas?

This is definetly a DNS problem. So for basic Network troubleshooting post the output of the following commands (best via paste.osmc.io):
ifconfig
route
cat /etc/resolv.conf
dmesg

Also do you have any addons or VPN installed that might mess with DNS?

You can not install OSMC this way on a Pi

OK:
ipconfig didn’t work because the related package doesn’t seem to be installed (and I won’t be able to install it as long as I don’t have internet).

~$ ipconfig
-bash: ipconfig: command not found

Since that issue happens only with OSMC installs obviously and just since a couple days, even with images I back-upped months before which always worked, do you think my internet provider might have screwed something here?

Well I know that Microsoft is a kind of brainwasher. But still you should be able to read that I wrote ifconfig not ipconfig :slight_smile:

Seems your DHCP server gave two DNS Servers in your LAN. Do you know if both of these IP’s are DNS servers?
I guess maybe the 192.168.10.3 is not working.

Try:
sudo nano /etc/resolv.conf
and delete the entry 192.168.10.3
Save with Ctrl-x

If that is not working then
sudo nano /etc/resolv.conf
just put in 8.8.8.8
Save with Ctrl-x

Wow fzinken - thanks a lot, you made my day!
The last hint did the trick, however both 192.168.10.2 (which is my actual DNS) and 192.168.10.3 did not work.
Can you tell me what 8.8.8.8 is actually doing?
And why only the particular OSMC setup had an issue with that, and none of my other PCs?

To tell the truth, I have no idea where OSMC had that second DNS value from. In my router config I couldn’t find anything.

P.S. Yes you got me right - I’m a Windows guy and mixed it up :slight_smile:

That’s a DNS server provided by google
This was just a temporary fix which will be gone by next restart

This is odd, I would not know why they don’t work. You need to figure that out

Well either OSMC was told so by the DHCP server or you had configured it manually on the GUI.

You know I have a router connected to the cable TV provider.
The problem here is that they can configure anything they like.
Last weekend I was declining their request on providing a public hotspot via my router, so I guess that technically something might have happened.
Maybe I will call them up to ask for any known DNS trouble related to their fiddling business :stuck_out_tongue:

For instance, that is the ipconfig output from the notebook I am just writing from, where these DNS issues don’t seem to make any problem:

Standardgateway . . . . . . . . . : fe80::8af7:c7ff:fe19:fc1d%8
192.168.10.2
DHCP-Server . . . . . . . . . . . : 192.168.10.2
DHCPv6-IAID . . . . . . . . . . . : 70824411

192.168.10.3
NetBIOS über TCP/IP . . . . . . . : Aktiviert

Ok, so your DHCP server distributes 192.168.10.2 and 192.168.10.3
One issue is that OSMC currently reverses the entries in resolve.conf therefore maybe that is the part of the issue.
But then it should work with if you reverse the order in resolv.conf. Maybe you want to try once more.

Bingo - turning the order around solves the issue.
Really strange, that it worked well until last weekend…
You write that OSMC currently turns it. So is that a known issue to be resolved?

But what is still strange:
Turning around DNS servers only works in SSH.
At the OSMC UI still no internet. There still I need to define 8.8.8.8 as secondary DNS (while 192.168.10.2 is the first one)

Well to be precise it is not OSMC but connman which OSMC is using for the network connectivity.
So connman knows about it but as they don’t consider it a major issue currently not high on the list to be changed. Generally this shouldn’t been an issue if your DHCP server distribute correct DNS Server.

This is really strange, suggest you may just configure the DNS in OSMC manually to overcome the issues. If you really don’t have a way to correct your DHCP only to distribute 192.168.10.2

Yeah, and since all Unitymedia customers complain anyway that their DNS is awfully slow, it’s even an improvement to keep the Google one as secondary :slight_smile:
Thanks a lot again for all your help.

Cheers,
Tim
