old 10.10 to new linux

1.

Since 10.10 is now unsupported, you have to use the server old-releases.ubuntu.com for everything. For example a line like:

deb http://es.archive.ubuntu.com/ubuntu/ maverick main restricted

Should change to:

deb http://old-releases.ubuntu.com/ubuntu/ maverick main restricted

Here is a complete /etc/apt/sources.list:

deb http://old-releases.ubuntu.com/ubuntu/ maverick main restricted
deb http://old-releases.ubuntu.com/ubuntu/ maverick-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu/ maverick universe
deb http://old-releases.ubuntu.com/ubuntu/ maverick-updates universe
deb http://old-releases.ubuntu.com/ubuntu/ maverick multiverse
deb http://old-releases.ubuntu.com/ubuntu/ maverick-updates multiverse
deb http://old-releases.ubuntu.com/ubuntu/ maverick-security main restricted
deb http://old-releases.ubuntu.com/ubuntu/ maverick-security universe
deb http://old-releases.ubuntu.com/ubuntu/ maverick-security multiverse

After updating your file:

sudo apt-get clean
sudo apt-get update

2.  sudo aptitude safe-upgrade

After a little research, what you probably want to use is aptitude safe-upgrade, which does install new kernels. Really! I double checked! :)
You should probably prefer aptitude in general to apt-get anyway, unless you specifically need something in apt-get.

3. sudo apt-get dist-upgrade
