At the risk of annoying the rest of the list, I'll repeat this...
type this at the commandline
sudo cat /etc/apt/sources.list <return>
type your password <return>
If the listings in the file now displayed on your screen look something
deb http://us.archive.ubuntu.com/ubuntu/ dapper main restricted
you'll never get anything but 6.06 updates.
at the commandline, type:
ls -l /etc/apt/sources.list
it needs to be write-able so it should look something like:
-rw-r--r-- 1 root root 2455 2007-07-06 19:54 /etc/apt/sources.list
(if it doesn't, then type: sudo chmod 644 /etc/apt/sources.list)
Now, do the following...
sudo nano -w /etc/apt/sources.list <return>
Password: <yourpassword> <return>
(nano is the editor, similar to notepad)
When nano opens, change every instance of dapper to edgy
When you've made all of the changes, type
Ctrl-X to exit. nano will ask you to write the file. Say 'y' ...
now you're back at the commandline... so type
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
when this is finished, all the files (and the system) should be upgraded
Once the system reboots, log in and go into a terminal and type
cat /etc/issue.net or lsb_release -r or whatever other linux command you
want to determine the version you're running...
repeat the process, except substitute feisty for edgy
