Description Alain Portal 2008-04-22 12:21:12 EDT
Description of problem:

When I click on a menu entry like "GNOME desktop" or "KDE desktop", I get 
immediately a popup which tell me "No network connection available", but 
network connection is OK.

Version-Release number of selected component (if applicable):

gpk-application-0.1.12 on Fedora 9 Preview KDE live x86_64

How reproducible:


Steps to Reproduce:
1. Install Fedora 9 Preview KDE live x86_64
2. Install network and check it works
3. In the "F" menu, choose Administration -> Add/Remove sofware
4. Click in the list in the left
Actual results:

A popup "No network connection available. Problem with loading repository 
metadata, this can be caused by network problems or repository 

Expected results:

I don't know, this is the first time I try to use this tools

Additional info:

The selected repos are:
Fedora 8.93 - x86_64
Fedora 8.93 - x86_64 - Updates

And if I unplug network from the laptop, it takes a long time before the popup 
Comment 1 Richard Hughes 2008-04-22 14:01:51 EDT
Are you running NetworkManager?
Comment 2 Alain Portal 2008-04-22 14:43:29 EDT
No, I setup network with system-config-network
Comment 3 Alain Portal 2008-04-22 16:34:43 EDT
Humm.. It seems I was wrong.
NetworkManager is running.

If I select only Fedora Rawhide as repository, the popup is different :
"No package cache is available.
Package cache was invalid and has been rebuilt."
Comment 4 Richard Hughes 2008-04-22 17:32:49 EDT
>Package cache was invalid and has been rebuilt

That's been fixed already, i just need to upload a new snapshot. Do you use
NetworkManager to connect your network, or use system-config-network? Do you
have the icon in the top right?
Comment 5 Alain Portal 2008-04-23 16:51:17 EDT
I first used system-config-network but I saw later that the NetworkManager
daemon was running.
There is no icon on the desktop but something labeled "Add widget - Zoom out"

What's the output of nm-tool?

Comment 8 Robin Norwood 2008-04-25 14:25:09 EDT
This sounds like a NetworkManager bug, then - it's reporting the network is down
when it isn't.  If I'm reading it right, eth0 is explicitly set to not managed
by NM, but still, it makes NM less useful if it's reporting of the
disconnected/connected status isn't accurate.

Assigning to dcbw for comment.
Comment 9 Dan Williams 2008-04-25 15:40:35 EDT
No, if the device is not managed by NetworkManager, _by definition_
NetworkManager is unaware of it's state and whether it has a connection.

Go into system-config-network, click on your device in the list, and check the
"Controlled by NetworkManager" checkbox, and save.  NM will now be able to
manage your device.
Comment 10 Alain Portal 2008-04-25 17:34:39 EDT
Checking "Controlled by NetworkManager" don't change anything!
And I don't like you close this bug without you really purpose a solution.

I'm tired about RedHat people who never listen to me.
You are « la goutte d'eau qui fait déborder le vase ».
Find a french people who be able to translate my anger!

I'm tired to never find a minimum of consideration.
I'll go to find it in another distribution.
I was a Redhat/Fedora user/contributor since I discover Linux 8 years ago.
Now, this is the end.
Comment 11 Robin Norwood 2008-04-25 21:26:06 EDT
If NetworkManager isn't going to be a reliable indicator of 'has a network
connection', then we need to change our logic to check for a network connection
differently, and not rely solely on NM.
Comment 12 Richard Hughes 2008-04-26 10:18:27 EDT
>la goutte d'eau qui fait déborder le vase

The last drop of water to make the vase spill? Or the last straw to break the
camels back? Either way I think maybe closing this bug might have been a little

What's difficult for us to do, is that you seem to be running the NetworkManager
service, and not using it - so even if we try to connect to NM and then fall
back to the output of "ping" - it will fail as NM would give a valid connection.

We could maybe check the res_query() status regardless of what system is used -
if you could help us add something like that it would be very appreciated, and
accepted upstream.

Comment 13 Dan Williams 2008-04-27 23:06:04 EDT
Robin: if NetworkManager is running, you use that for indication of network
connectivity.  If NM is not running, then some other method must be used.

If the user has unmanaged a device, that's their problem, and not something that
we are really going to "support".  Users who unmanage devices from NM know
enough figure stuff out for themselves.  The largest reason for this in the past
was static IP, which NM 0.7 certainly supports.
Comment 14 Robin Norwood 2008-04-28 12:02:55 EDT
Dan - oops, sorry, I meant to reopen this and reassign it back to me. By 'change
our logic' in comment #11, I meant change PackageKit's logic, which right now
says (IIRC):

"If NetworkManager reports no connections, don't even try to get updates."

IOW, using PackageKit requires that the user use NetworkManager.  This probably
isn't a reasonable requirement for all users, so we should either address it in
PK or explicitly declare that using PK requires that the user use NM.  Not
NetworkManager's bug at this point, so assigning back to me.
Comment 15 Dan Williams 2008-04-28 12:09:35 EDT
Robin: ah, I see.  IMHO, correct behavior is:

1) If NM service is running: query NM for active connections, do the right thing
with GSM/CDMA, etc too since you can actually get that information out of NM.

2) If NM service is not running, scrape routing table for the default route.  If
there is a default route, assume a connection to the internet.  If no default
route, assume no connection.  But allow the user to force a PK update if they
want through the "Update System" dialog.
Comment 16 Alain Portal 2008-05-01 04:29:49 EDT
I updated with gnome-packagekit-0.1.12-5.20080416git.fc9.x86_64
There is no more the message "No network connection available".
Now, when I click on a software group, I get "No results were found" in the
right window of gpk.
The only selected repository is "Fedora - Rawhide".
Sorry if there is something that I don't understand but as I'm still on FC6 on
other PC, there is the first time I try to use gpk.
Comment 17 Alain Portal 2008-05-01 04:47:26 EDT
I updated my system with gpk-update-viewer, so now, if I'm running it, it tells
me of course "There are no updates available".
But if I click "Refresh", I get "No network connection available".
Comment 18 Richard Hughes 2008-05-01 06:26:08 EDT

>If NM service is not running, scrape routing table for the default route.
>If there is a default route, assume a connection to the internet.
>If no default route, assume no connection.

How do I trivially grab the default route? I'll add the fallback code today. Thanks.

Something like this should fix up the network detection problems when we are
not using NetworkManager.
