I'm trying to disable the proxy for apt-get but it seems like apt-get gets it's proxy configuration from somewhere else other than /etc/apt/apt.conf, because although the apt.conf file is empty (and the system proxy set to None) it's still trying to connect to the proxy.

Anyone got an idea?

I'm using a script to replace different configuration files in order to easily switch between proxy and non-proxy environements. The problem was that I replaced the proxy apt.conf file with an empty apt.conf file, which apt then ignored.

Works for current latest Ubuntu as well.

If the proxy conf does not exist, create it:

$ sudo touch /etc/apt/apt.conf.d/95proxy.conf

Then add the following two lines:

Acquire::http::Proxy "false";
Acquire::https::Proxy "false";

If you do not want apt-get to use a proxy, use apt-get as:

sudo apt-get -o Acquire::http::proxy=false <update/install>

Sometimes, there are proxy environment variables that are still set.

To find out, do the following command:

env | grep proxy

If you see some output, for example:

http_proxy=http://127.0.0.1:1234/

Then you'll need to unset this variable.

To do so, execute the following command:

unset http_proxy

Follow the same approach for all the other entries, such as https_proxy.

    Thanks for the hint, unfortunately both the http and the https proxy are empty :\ – Ahatius Sep 13 '13 at 08:45

    Hmm. Interesting. Although I doubt it, but maybe the variable is HTTP_PROXY (all caps), so try env | grep -i proxy (-i meaning "case insensitive"), and see if there's any output; it's worth a try =/. Also, can you do grep -iR proxy /etc/apt/? This searches for the word proxy in all files under /etc/apt/, because the proxy is sometimes set in a file under /etc/apt/apt.conf.d/. – Alaa Ali Sep 13 '13 at 09:24
  • It also doesn't have to do with proxy being all caps. Executing the grep command also didn't reveal any other file that contains a proxy configuration. – Ahatius Sep 13 '13 at 18:01
  • Ok, I think I got it. I'm using a script to switch all configuration files for proxies. The problem was that I replaced the apt.conf with an empty file. Apt then obviously always loaded the last proxy configuration, because the proxy value was not set to false. Thanks anyway for your efforts! – Ahatius Sep 13 '13 at 18:09
  • Maype the proxy env has setting in /etc/environment , so we can looking for here. – Chu-Siang Lai Nov 03 '14 at 03:59

There isn't only one place where apt-get read configuration files. You should run grep -i proxy /etc/apt/apt.conf.d/* and it will give you the exact file that has the proxy settings (this is just an example running with update instead proxy:

grep -i update /etc/apt/apt.conf.d/*
/etc/apt/apt.conf.d/20apt-show-versions:// When Apt's cache is updated (i.e. apt-cache update)
/etc/apt/apt.conf.d/20packagekit:// Whenever dpkg is called we might have different updates
/etc/apt/apt.conf.d/20packagekit:// i.e. if an user removes a package that had an update
/etc/apt/apt.conf.d/20packagekit:"/usr/bin/test -e /usr/share/dbus-1/system-services/org.freedesktop.PackageKit.service && /usr/bin/test -S /var/run/dbus/system_bus_socket && /usr/bin/gdbus call --system --dest org.freedesktop.PackageKit --object-path /org/freedesktop/PackageKit --timeout 1 --method org.freedesktop.PackageKit.StateHasChanged cache-update > /dev/null; /bin/echo > /dev/null";
/etc/apt/apt.conf.d/20packagekit:// When Apt's cache is updated (i.e. apt-cache update)
/etc/apt/apt.conf.d/20packagekit:"/usr/bin/test -e /usr/share/dbus-1/system-services/org.freedesktop.PackageKit.service && /usr/bin/test -S /var/run/dbus/system_bus_socket && /usr/bin/gdbus call --system --dest org.freedesktop.PackageKit --object-path /org/freedesktop/PackageKit --timeout 1 --method org.freedesktop.PackageKit.StateHasChanged cache-update > /dev/null; /bin/echo > /dev/null";

    This is not enough, the file /etc/apt/apt.conf also can contain Proxy information. Also it may be written with capital letter. – kap Oct 11 '19 at 13:47

It's possible the environment variable http_proxy is set to some proxy. try clearing the variable (or at least look if it has a value)

Stupid way of making it work is disable the proxy for a while using system settings > Network .

Or remove the proxy config from /etc/environment and /etc/apt/apt.conf

enter image description here

And add the manual proxy config back once you need proxy back.

For me, no proxy variables were set in the environment, and no proxy was set at the system level. However, a file 01proxy was present in /etc/apt/apt.conf.d/ which contained the line Acquire::http::Proxy "http://PROXY:PORT";. Commenting the line with # (or deleting the file) worked for me. This means that other files in apt.conf and apt.conf.d may contain proxy settings and I'd suggest greping proxy (with -i flag) information from those two folders to know if the apt service uses one.

Note that @Prashant Adlinge answer always works in that case as it bypasses any configuration file.

you should bypass all proxy settings:

sudo apt-get -o Acquire::http::proxy=false -o Acquire::https::proxy=false -o Acquire::ftp::Proxy=false update
sudo apt-get -o Acquire::http::proxy=false -o Acquire::https::proxy=false -o Acquire::ftp::Proxy=false install xxx
