I set the network proxy as per the system settings GUI but this is not picked up by ubuntu one or update-manager - I just get failed to update repository information.
Even apt doesn't work. I then added a 01proxy config file manually in /etc/apt/apt.conf.d/ with:
Acquire:http { Proxy "http://whatever:1234"; };
I could then run apt-get successfully. But still not the two packages above. Why aren't the system settings working?
