Re: Connect to eth0 or wlan0 (NetworkManager from the command line?) - Wheezy
# service network-manager stop
Edit /etc/network/interfaces and set the following. You can simply
uncomment the "#NetworkManager#iface eth0 inet dhcp" line. See
for the details of that particular line. See this next
for general information about that file.
iface eth0 inet dhcp
Plug in your ethernet wire. Bring up the interface.
# ifup eth0
You should be able to watch the progress by tailing the syslog in
another window. (Hint: Alt-F2 gets you to the second virtual console
terminal.) After it is up something like 'netstat -nr' should print
useful network information about the network.
At that point you should be up and on the network and can re-install
anything that you want. That should get your system going.
The /var/log/dpkg.log could be useful in seeing what was recently
uninstalled. Also /var/backups/ contains dpkg.status* and other files
that should allow you to know what was previously installed and
therefore be able to get back to a known good state.
# apt-get install dctrl-tools
$ grep-dctrl -s Package -n "install ok installed" /var/backups/dpkg.status.0
...dumps a list of previously installed packages...
$ grep-status -s Package -n "install ok installed"
...dumps the current list of packages installed now...
Putting that information to use you can see what was different between
the backup file and now.
$ grep-dctrl -s Package -n "install ok installed" /var/backups/dpkg.status.0 | sort > /tmp/list.prev
$ grep-status -s Package -n "install ok installed" | sort > /tmp/list.now
$ comm -3 /tmp/list.prev /tmp/list.now
And then inspecting that list make a decision about how to repair.
Whew! That above is somewhat complicated. But if you are in a hurry
then you probably you just need the following to pull in what you
lost. These metapackages (and gdm I prefer over the gdm3) will
probably pull in what you need. But the above would give you exact
# apt-get install gnome gnome-core gnome-desktop-environment gdm
Hope that helps,
Thank you so much for such a great and comprehensive answer.
Googling around i thought of simply uninstalling NetworkManager, as i wasn't sure how to stop services.
Also, /var/backups was exactly what i was hunting for but simply couldn't find. Muchas gracias for referencing that (and /var/log).
And lastly, dctrl-tools is awesome! +1 thanks for that, too!
And nothing ventured, nothing earned... i'm currently (and graciously) diving into all of this!
