Latest pip 8.1.2 fails to upgrade on Ubuntu 16.04

[sethmlarson]

• Pip version: 8.1.1
• Python version: 3.5
• Operating System: Ubuntu 16.04

Description:

Tried to upgrade pip 8.1.1 to 8.1.2 for Python 3.5, downloaded the wheel for pip 8.1.2, but still displays version of pip as 8.1.1. This happens regardless of if I remove cache or used the cached wheel. Many others are having a similar problem: http://askubuntu.com/questions/775942/latest-python-pip-with-u16-04

What I've run:

$ python3.5 -m pip install --upgrade pip
Collecting pip
Using cached pip-8.1.2-py2.py3-none-any.whl
Installing collected packages: pip
Successfully installed pip-8.1.1
You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Can you re-test this and paste the full commands you ran and their output, and why you think you don't have pip 8.1.2? I just tried running this command locally, and I got:

njs@a08469421425:~$ pip3 install -U pip
Collecting pip

You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
njs@a08469421425:~$ pip3 install -U pip

njs@a08469421425:~$ pip3 --version
pip 8.1.2 from /home/njs/.local/lib/python3.5/site-packages (python 3.5)

So I got the same output, but pip was in fact upgraded to 8.1.2. (It's definitely a bug that it said "successfully installed pip-8.1.1" -- I have no idea what's up with that, someone who knows pip better than me might. And probably it should be considered a bug that after upgrading pip, pip complains about being an old version -- but this is just confusing, not actually a problem, what pip is saying is that the version of pip you're running is 8.1.1, not that the version of pip you just installed is 8.1.1.)

[njsmith]

Also, if I try using python 2.7's pip, like in the linked askubuntu question, I get:

njs@8bde0cc97ff7:~$ pip install --upgrade pip
Collecting pip
  Downloading pip-8.1.2-py2.py3-none-any.whl (1.2MB)

njs@8bde0cc97ff7:~$ pip install --upgrade pip
Requirement already up-to-date: pip in ./.local/lib/python2.7/site-packages
njs@8bde0cc97ff7:~$ pip --version
pip 8.1.2 from /home/njs/.local/lib/python2.7/site-packages (python 2.7)

So not only does that work, but it also avoids the weird output issues I saw with the xenial pip3.

I think this is going to be because Ubuntu patches their pip to prevent it from modifying packages installed with apt.

[edwinksl]

@njsmith: I get the "You are using pip version 8.1.1, however version 8.1.2 is available. You should consider upgrading via the 'pip install --upgrade pip' command." message for pip for both Python 2 (pip) and Python 3 (pip3). For Python 2, pip --version gives pip 8.1.2 from /home/edwinksl/.local/lib/python2.7/site-packages (python 2.7) and for Python 3, pip3 --version gives pip 8.1.2 from /home/edwinksl/.local/lib/python3.5/site-packages (python 3.5). Therefore, it does seem that pip has been successfully upgraded from 8.1.1 to 8.1.2 for both Pythons despite the (misleading) warning messages.

The issue here is I don't know if the bug with the erroneous warning messages lies with pip itself or with the Ubuntu patches for pip as suggested by @dstufft.

[dstufft]

Oh right, it installing into --user, I forgot Ubuntu applied that patch, if you're still getting that error message, it might be because of wonky sys.path. What does python -c "import pip; print(pip.__version__)" give you?

[edwinksl]

@dstufft python -c "import pip; print(pip.__version__)" gives 8.1.2.

[dstufft]

Interesting... and you're still getting that "you're using 8.1.1 but 8.1.2 is available" message?

[edwinksl]

@dstufft I only got that message on the first invocation of pip install -U pip for Python 2 and pip3 install -U pip for Python 3. Subsequent invocations gave Requirement already up-to-date: pip in ./.local/lib/python2.7/site-packages for Python 2 and Requirement already up-to-date: pip in ./.local/lib/python3.5/site-packages for Python 3.

[dstufft]

Ah- Ok then I think that's just a bug that I think we have open somewhere else, where upgrading sometimes doesn't indicate the newest version until after the processes has completely exited.

[edwinksl]

@dstufft That makes sense to me, thanks!

[jelabarre59]

Same thing here. python -c "import pip; print(pip.version)" reports "8.1.2", yet I still get the error. Unless it's because the command I need to run (STATIC_DEPS=true sudo -H pip install lxml==3.6.0) is calling it with sudo?

[scotmatson]

Just contributing to make some additional noise regarding this issue. The upgrade fails for me as well, additionally, uninstalling pip3 and reinstalling results in version 8.1.1, not 8.1.2.

[nikhilgoyal22]

does sudo -H pip install --upgrade pip work for anyone?

[adrian-jasinski]

Not working on ubuntu 16.04

sudo -H pip install --upgrade pip

[adrian-jasinski]

It working:

wget https://pypi.python.org/packages/e7/a8/7556133689add8d1a54c0b14aeff0acb03c64707ce100ecd53934da1aa13/pip-8.1.2.tar.gz

tar -xzvf pip-8.1.2.tar.gz

cd pip-8.1.2

sudo python setup.py install

admed
thank you

[xavfernandez]

As the real issue seems to be the old version reported when installing the new version, I'm closing this issue as duplicate of #3049, #2382 and #3709

[Sparrow1029]

Hi there! I had the same problem on Linux Mint 18, finally found the answer on pip's homepage! This method worked for me. Hope it helps!

[stevenfrancisco]

You might have multiple Python Versions installed. I'm running Ubuntu 16.04 and finally figured that I needed to upgrade the pip in both python 2.7 and 3. Since I run them side by side, I needed to specify pip3

pip3 install -U pip

[aospan]

same issue on 'Ubuntu 16.04.1 LTS'. but following commands helps:

apt-get remove python3-pip python-pip
pip2 install -U pip
pip3 install -U pip

now it's ok:

# pip install --upgrade pip
Requirement already up-to-date: pip in /usr/local/lib/python2.7/dist-packages
# python2 -c "import pip; print(pip.__version__)"
9.0.1
# python3 -c "import pip; print(pip.__version__)"
9.0.1

[quinncomendant]

I was getting the same error of Certbot has problem setting up the virtual environment and You are using pip version 8.0.3, however version 9.0.1 is available when running certbot-auto via cron. Running certbot-auto regularly (as root) works fine. To solve this I had to add export HOME=/root to the start of the cron command, like this:

48 */11 * * * export HOME=/root; /root/bin/certbot-auto renew --quiet --no-self-upgrade

[dzumret]

I removed first pip3 with:

sudo apt remove python3-pip

Then installed with:
python get-pip.py

Full process flow to install latest pip: (some steps may be redundant if you already have pip installed but no harm done)

sudo su                               # become root
cd                                    # prevent trashing your user's python cache permissions
apt-get install python3-pip           # bring in easy_install3
pip install --upgrade pip             # cache latest pip sources
apt-get remove python3-pip python-pip # remove Ubuntu's pip
easy_install3 pip                     # install up to date vanilla pip
pip --version                         # verify it
exit                                  # back to your user.

[htdinh]

This works for me in Python 2.
sudo apt-get purge --auto-remove python-pip
Then follow steps by @sc00ut above.

[dotw]

This works for me too. Following the steps of @Dinh-Hung-Tu & @sc00ut
and the latest step is
hash -r
to refresh cache

[LF-DevJourney]

apt update && upgrade python3-pip

[zkhodzhaev]

thank you admen, it worked.
