Upgrade from Xubuntu 10.04 LTS to 12.04 LTS

Here are the couple things that I found that I had to fix when upgrading from Xubuntu 10.04 LTS to 12.04 LTS:

1. I was not getting DNS resolution

• sudo vi /etc/resolv.conf

• add:

  nameserver 192.168.1.1 

• UPDATE: the above does not last you should instead:

• sudo vi /etc/network/interfaces

• add:

  dns-nameserver 192.168.1.1

2. My VNC session was not loading a window manage (giving a failure to load gnome message -- I also got a trash not supported error and application crashes when starting xfce4-session)
• vi ~/.vnc/xstartup
• make sure it has:

  startxfce4 &

3. When running synaptic from the application menu, it would ask for a password then fail to load 

• xhost +localhost

4. noip2 was removed and not in the package list

• cd /usr/local/src

• sudo wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz

• sudo tar xf noip-duc-linux.tar.gz

• cd noip2-2.1.9-1/

• sudo make install

• sudo /usr/local/bin/noip2 -C

• sudo vi /etc/init.d/noip2

• change:

  DAEMON=/usr/local/bin/$NAME

  CONFFILE=/usr/local/etc/noip2.conf

• sudo /etc/init.d/noip2 start
