Public bug reported:
I've been installing Ubuntu Command Line systems using the Alternative
installer, then adding e.g. lubuntu-core, lubuntu-desktop ubuntu-desktop
to wipe old machines and bring them up to date as part of a Laptop
Shrimping project.
I developed this approach as a workaround for bug 424643 meaning I can
roll back the install of a particular desktop if the machine has trouble
with it (typically resource limitations). I assumed naively that
installing Ubuntu in "install a command line system" mode followed by
installing ubuntu-desktop would have the same effect as a full install.
Most of the time, this seems to be the case.
I've discovered, however, that even with exactly the same packages
installed in the end, the network connection is misconfigured (ping
doesn't work) on some machines when following the command line route.
On two machines, (the Dell Q15R N5110 which I used to apport this bug
after a successful install, and the Fujitsu Lifebook P1510 which
clarebowman22 used to apport bug 1014263), this error was consistently
experienced through several installs based on Precise, installing
lubuntu-core, ubuntu-desktop or lubuntu-desktop in various combinations
and sequences starting with a command line system, then using apt-get to
bring up a desktop. Each case led to a desktop which experienced bug
1014263. Nothing but a full wipe and Ubuntu install from scratch will
cure the problem (as demonstrated by the Dell which had a previously
non-functional network and is now able to apport over wireless).
I've tested this by repeating the same install on the same machine with
the same medium using the alternative installer for Ubuntu Precise
through the two different routes - either starting from a command line
install, or going for the full install mode.
To summarize bug 1014263, the desktop installed on top of a command line build
through...
sudo apt-get update; sudo apt-get dist-upgrade; sudo apt-get install
ubuntu-desktop
...has a wireless network which bizarrely fails to work, even though it can
apparently complete a Wireless scan and handshake with a WPA network, no ping
packets are exchanged with www.google.com afterward.
Coupled to this behaviour is a long timeout during boot during which
Plymouth reports something like "waiting 60 seconds for network
configuration". Also associated seems to be the disappearance of the
networking icon in lxpanel, and the claim that the eth0 adapter is "not
managed" when trying to control it through a network applet.
Something about the sequence of running a command-line system and apt-
getting over ethernet, versus doing your first boot direct into a full-
fledged Ubuntu desktop, must change something mysterious about the
networking configuration.
