I wasn't aware of that Edition prior to your comment (above).
A Google search is not clear how the CE tracks (or follows) "normal"
Ubuntu releases, so as a friendly tip it'd be useful to know what Ubuntu
release your system believes itself to be so it'd be easier to supply
release-specific help as required.
Four commands need to be typed in a terminal window to fully identify
your system and its release. To enter a terminal window, this:
Applications -> Accessories -> Terminal
works from the top menu bar in a standard Ubuntu release using Gnome.
These are the four commands to be entered in a terminal window:
cat /proc/version
uname -a
cat /etc/issue
lsb_release -a
Here is the output from my system as an example:
thad@ubuntu:~$ cat /proc/version
Linux version 2.6.24-21-generic (buildd@palmer) (gcc version 4.2.3
(Ubuntu 4.2.3-2ubuntu7)) #1 SMP Mon Aug 25 17:32:09 UTC 2008
thad@ubuntu:~$ uname -a
Linux ubuntu 2.6.24-21-generic #1 SMP Mon Aug 25 17:32:09 UTC 2008
i686 GNU/Linux
thad@ubuntu:~$ cat /etc/issue
Ubuntu 8.04.1 \n \l
thad@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 8.04.1
Release: 8.04
Codename: hardy
From the output of the above commands, my system is release 8.04.1,
codenamed "Hardy", the system is named "ubuntu", and the running
kernel is version 2.6.24-21-generic. For most help requests, only the
release number is important (either "8.04" or "8.04.1" from the above)
since there are differences between releases.
