installing pip3 (for python3) on ubuntu 16.04 LTS using a proxy

Question

I have tried entering:

sudo apt install python3-pip

The error I get is:

$ sudo apt install python3-pip

I believe we have bypassed the proxy, so I'm not sure why I'm getting '404 file not found'.

Solution 1

The first procedure you followed is correct

sudo apt-get -y install python3-pip

But before installing try to update using command

sudo apt-get update

If first did not work then you can also do this using curl

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python3 get-pip.py --user

Then to verify installation try

pip3 --help 

For checking version :

pip3 --version 

Solution 2

I fixed such problem by changing Server in "Software & Updates" -> Download from: there I chose different address and 404 disappeared.

Solution 3

what worked for me

curl -sS https://bootstrap.pypa.io/get-pip.py >>setup.py
python3 setup.py

Try again running sudo apt-get update

Works from home fine, but I have Linux machines at the school I teach at, which have a proxy which I thought we had bypassed for ubuntu.com, but looks like I haven't somehow...

[Abisdad]

Thank you! But it needed: "pip3 --help"

[PvdL]

curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python

[TiloBunt]

what address did you choose? please add more details

[Charlie Parker]

Interesting! Why do you need the 'sudo apt-get update' to install pip3? seems rather unexpected to me.

This does not work for pip3, it installs pip2 script which python3 can't run.

curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3 for Python 3 ;)

[Ahmet Erkan ÇELİK]

working with "sudo python get-pip.py" for me. Thanks!

In case of error: ImportError: cannot import name 'sysconfig' install the python3-distutils first. Like this apt install python3-distutils
