Public bug reported:
Binary package hint: network-manager
Executive summary: network-manager does not consider the computer to be
online if all connections are "unmanaged".
Details:
I have a computer, upgraded from 9.10 to 10.04LTS.
There is a regression WRT network-manager after upgrade, in that
applications such as pidgin or firefox believe the computer to be off-
line when in fact it has a working Internet connection through Ethernet.
Firefox starts in off-line mode, and Pidgin waits for a connection
before it even attempts connecting to the XMPP (Jabber) server. This
behaviour was NOT observed with Ubuntu 9.10, but is NEW WITH 10.04LTS
after upgrade.
apt-cache policy:
network-manager:
Installed: 0.8-0ubuntu3
Candidate: 0.8-0ubuntu3
Version table:
*** 0.8-0ubuntu3 0
500 http://de.archive.ubuntu.com/ubuntu/ lucid/main Packages
100 /var/lib/dpkg/status
The computer uses a static network configuration through
/etc/network/config. nm-tool (before uninstall) logged two "unmanaged"
connections, eth0 and wlan0.
The whole situation was unacceptable so I started looking for
workarounds. The blunt obvious solution was purging all traces of
network-manager from the computer and reboot. Now Firefox comes up in
online mode, and Pidgin tries to connect to the XMPP server and
succeeds.
I would have expected that network-manager considered the computer to be
online, even in the presence of only "unmanaged" connections, if at
least one of those has link beat.
