I had the same problem with Update Manager but also noticed that:
- I had the system wide proxy set
- on a shell this resulted in variables all_proxy, ftp_proxy, http_proxy, https_proxy and no_proxy being set and exported
- the values are passed to sudo, i.e.:
$ sudo echo $http_proxy
returns the correct setting
- BUT when I try to:
$ sudo apt-get update
connecting to servers fails!
- HOWEVER if I choose to:
$ sudo su
# apt-get update
it works!!?
With Aghast's workaround '$ sudo apt-get update' is working OK as well as the Update Manager.
Thank you Aghast for the workaround!
