Comment 9 for bug 319146

I am affected by this. I have installed Ubuntu on many computers for people that just wanted a basic computer. Ubuntu was perfect for them, and I rarely get any calls for help. Many of these users would want me to handle any major upgrades. I shouldn't have to keep records of who has what version.

The user should have an early warning about end of life.
Technically this could be considered a security issue since the user is not made aware that they are vulnerable to exploits.
The current notification that a new distribution is available does not inform the user that they must upgrade.
Some users do not want to perform the upgrade themselves. An early warning can let them notify the person that will handle the upgrade for them in advance.

I would suggest giving the user 3 months notice: "Support for this version of Ubuntu will expire in _ months. Please take measures to upgrade soon."

The implementation of this shouldn't require internet access since EOL is determined prior to the release, and some users don't have an always on connection.
This check can also be independent of the update-manager in case the automatic update checks are disabled.

Security should be pro-active. Informing users on how to perform upgrades after EOL is retro-active.
I don't understand why anyone would argue against this. I am sure implementing this would be a simple task, and would not interfere with users that keep up with their upgrades.
