When attempting to do the System upgrade from 13.2 to Leap 42.1 I followed all the steps at https://en.opensuse.org/SDB:System_upgrade. Everything went smoothly until I executed ‘zypper dup --download in-advance’ from within runlevel 3 as root. Once the system attempted to download the files for 42.1 I received a curl error that the download.opensuse.org domain was not available. Is there a solution to this problem or was it just a bad time to try to upgrade ( Sunday 12pm EST ).
I have a backup of my OS 13.2 partitions I can easily restore but maybe I can just attempt the ‘zypper dup --download in-advance’ command again later if I can understand why it was not previously working.
Nonetheless I can connect to the Internet without any problems.
Do you think this is because http://download.opensuse.org is down or could there be some other fundamental reason ?

That’s presumably your router. It seems that your router is not resolving download.opensuse.org.
You might need to configure a different resolver – say one or two of the google public dns servers. Or add an entry to “/etc/hosts”.
I’m currently using (in “/etc/hosts”):
195.135.221.134 download.opensuse.org
I don’t actually have a resolver problem. I’m using that, because otherwise I connect to the repos with IPv6, and then I am referred to really slow mirrors (the geolocation stuff isn’t working well for ipv6).
What I discovered is that pinging download.opensuse.org works fine from a console window after the normal graphical login, but when I switch to runlevel 3, which the System Upgrade documentation strongly recommends for upgrading the system before the ‘zypper dup --download in-advance’ command, then pinging download.opensuse.org returns the “unknown host download.opensuse.org” message. I am following the documentation at https://en.opensuse.org/SDB:Switch_runlevel to switch to runlevel 3 in virtual terminal 2. So either the documentation for the System Upgrade is wrong or there is something wrong with my setup when running at runlevel 3.
I suspect that gogalthorp is right about that. When you switch to runlevel 3, the NetworkManager connection goes unless you have shared the connection with all users.
Instead of switching to run level 3, just use CTRL-ALT-F2 to get a console terminal session. Or, better, share the connection with all users. Or switch to “wicked” at least during the upgrade – you can switch back later.
Yes, NetworkManager is running, but has disconnected. Unless you have a shared connection, then it is disconnected when you logout. And switching to run level 3 is a forced logout.
An ethernet connection is, by default, shared.
Otherwise, from the desktop, you can edit the connection and set it to be shared by all users. This does require the root password.
Or, from Yast, you can switch to using “wicked” instead of “NetworkManager” (on the global tab). You will have to configure the WiFi password there. That’s a connection that will continue at run level 3.
It’s a Wifi connection, not an Ethernet connection.
Are you saying that at run level 3 only “wicked” will work to maintain a connection for root ? If not
I can ‘su -’ to root or login as root. How do I edit the NetworkManager connection so it will be shared by all users so I can upgrade as root, which is what the SystemUpgrade wants me to do ?
I am using KDE. I don’t remember what I originally did to setup the WiFi connection. I think something popped up with a list of nearby WiFis, I chose the one that was mine, filled in the WiFi WPA2 password, and everything just worked after that.
There’s an icon in the tray that you must have clicked. Move your mouse point over the various tray icons, one at a time, till you find one that mentions your network connection. Then click on that, and click the tool (wrench) to make changes. You need to edit your connection. And one of the choices is to share the connection with all users. That’s the change that keeps you connected even after logout from your desktop session.
I find the icon for the WiFi connection and was able to set it to allow all user to use the Wifi. Afterwards when I switched to virtual terminal 2 via Ctrl-Alt-F2, logged in as root, then changed the runlevel to 3, and relogged in as root I was able to access download.opensuse.org successfully and do the upgrade using ‘zypper dup --download in-advance’ successfully.
