1.1.1- installer has been working fine until today when ever i tried to install or uninstall or refresh sources or anything i just got an error message -package download failed-. I tried rebooting and refreshing sources.....cleared Q. Nothing worked. WIFI is working so i'm not sure what it is.....any ideas on a fix.
B) Is there a way to reboot installer without having to unlock it all over again.

just do a search for installer fix in this section.
