Ubuntu 16.04 apt-get - Could not resolve 'proxy_server'
Solution 1
It looks like you have inherited the information from the DHCP server.
Check the APT file (you have already done it) under /etc/apt/apt.conf
and remove any Acquire::XXX::proxy
where XXX
is http
/ https
/ ftp
In addition to this, check /etc/environment
for proxy information.
Last but not least, try to renew your DHCP information, it can eventually help: sudo dhclient -r
One last word, are you using the same BASH shell process you were using at the university or you opened a new one? Because, it could have cached information.
Solution 2
This worked for me :
go to /etc/apt/apt.conf.d
using :
cd /etc/apt/apt.conf.d
then check the files available there using :
ls
goto the proxy file: would have a name like 40proxy or 10proxy etc
open it using:
sudo gedit
now
delete all content and save it.

Earlier, I was at my university and accessing the internet through a proxy server i.e.
proxy.iiit.ac.in
. But, currently I am trying to runsudo apt-get update
from my home internet (which as no proxy server) and I am getting the following error message.I have removed the system and terminal proxies, and I have also removed proxies from
apt.conf
in/etc/apt/
. What is it that's still causing the problem?
