Comment 1 for bug 1397297

Hello,

Apologies for this, the problem is that Ubuntu 14.04 qualifies as an "old" release since it's been superseded by 14.04.1, but the releases server has not been updated accordingly.

This is something outside my control, so I will need to mark this bug as Invalid for the ubuntu-certification project.

However, rest assured we're working with the Ubuntu release team and server maintainers to correct this situation as soon as possible.

Meanwhile, you can of course download 14.04 here:
