Fedora 10 installation: network problem on software updates
 

I have installed Fedora 10 to an Acer4000WLMi laptop (with both Ethernet and WiFi connectivity). The laptop is a dual-boot WinXp / Fedora 10 box; there are no issues with the WinXP installation and booting into either OS works fine.
Detailed system information:
In the main the installation was problemless (I am not previously familiar with Fedora but I am a long-time CentOS user and experienced in several flavours of UNIX.)

However ... when I try to install/update packages using:

System > Administration > Add/Remove Software

the app goes away and resolves dependencies as expected. But when I come to hit the Install button I get the message that installation cannot continue because the system is not online.
Specifically the message "No network connection available" and the More
Details tabs offers "Cannot install when offline".
This is a puzzle because in parallel to doing this I am actively looking at web-pages and sending/receiving email and other online activities.

My /etc/sysconfig/network-scripts/ifcfg-eth0and /etc/sysconfig/network-scripts/ifcfg-eth1 configuration files appear to be fine and are clearly working (at least the wired connection, I am not concerned with the wireless at the moment) otherwise how is web access and email etc working successfully?

I do notice the NetworkManager icon in the panel bar has a cross in a red background against it and that everything is greyed out, other than VPN Connections. Neither of Wired and Wireless Connections can be selected and the display says "device is unmanaged".
Yet I have installed and activated NetworkManager (as far as I can see).

Another idiosyncrasy I have noticed is that the when I start up Firefox it comes up in "Offline Mode" and obviously the homepage link is not reached and I am invited to "Try again". However as soon as I set Firefox to "Online" I immediately get the home page - i.e. so the internet access is established with no other action on my part, in other words network connectivity is already established.

Where do I start to look to resolve the problem? I've had a look on the forum and not been able to find anything similar.
It is severly limiting as I am unable to install new applications, or upgrade existing ones, by this means (Add/Remove software).

Many thanks in advance for any assistance/suggestions.

Try updating / installing via command line.

use or if this also results in connection failed errors, you may want to check that dns resolution is working fine. use dig / host to debug.

Fedora 10 (the fresh install) is known to have problems with package updating, with yum and with the GUI network settings tool. This topic has actual been dealt with a couple of times in the last few days here on LQ:

Have a look and see if it helps you.

Many thanks for the reply.
Indeed I have used:
and there are totally no problems with doing that - it works every time.
But if I want to use the GUI tool I cannot (and it is usually easier to use the GUI tool if I want to install multiple packages in a particular area).
It is the fact that the network connection is fine for one but not the other that I find puzzling (and would like to cure!)

Many thanks. Shall check them out.

I checked them out and it made no difference. In fact in both links cited it did not appear to make much difference either (one stated that it did not work and the other didn't confirm either way).
