LL3.0: "couldn't fetch the package cache information lists"

[LL-user]

Hi Mike,

You tried to install f.lux. If you deactivate/delete that repository you should be fine.

As a better - cause also error free - alternative I recommend to install gtk-redshift. It is included in the repositories, i.e. doesn't need another PPA. If you use your computer also offline and want it working you need to create a config file - let me know if you need help. Otherwise just start it up

Hope that helps
