Public bug reported:
Binary package hint: network-manager
I install Maverick (10.10) on a new computer. I boot it, and I don't get
any network connectivity on the very first start. That is no good way of
starting a new installation...
What seems to have happend is this:
In /etc/network/interfaces, apart from the loopback stanza, the following is
added:
auto eth0
iface eth0 inet manual
Combined with /etc/NetworkManager/nm-system-settings.conf containing:
[ifupdown]
managed=false
this effectively means that NetworkManager does not "see" eth0. For some
reason, this seems to prevent the GNOME Network Manager applet to
appear, even though I have a wireless card as well (which shows up in
the NM applet after I fixed the eth0 problem).
This has happened on at least four computers, one desktop and one
laptop, and also a co-worker on his laptop, and finally on a virtual
installation in VirtualBox (to test this behaviour again). The co-worker
found out one workaround, by changing the NM config file to
"managed=true". I tried to remove the eth0 part of
/etc/network/interfaces, which worked as well. Comparing with older
versions of Ubuntu, which has managed=false but no eth0 information in
interfaces, this seems like the preferrable fix.
There seems to be several issues at work here.
First of all, why did I get the eth0 stuff in my interfaces file during
installation? (The major problem)
Second, why did this stop Network Manager from managing my wifi card?
I am happy to provide whatever extra information is needed to solve the
bug.
All of these computers were connected on a company network which
requires a proxy to connect to the outside world. I don't know if it is
relevant, but it might be. Also, several people here (including me) have
been using Ubuntu for a long time on this network, and this has never
happened before, on anything between Jaunty and Lucid. And yes, we do
have a DHCP server on the network.
