Linux Mint 17 Cinnamon: Update managers gives error msgs in trying to find f.lux PPA URLs

[tinker123]

Linux Mint 17, Cinnamon desktop

Hi,

A few weeks ago my update manager started complaining that the PPA URLs
for f.lux no longer work. Here is a screenshot:

Can anyone tell me what URLs I should switch to or what would be the better place to ask?

Thanks
