I can't use pip on WSL Ubuntu

[hwooo]

Please fill out the below information:

• Your Windows build number: 10.0.17763.475 / WSL Ubuntu 18.04.2

• What you're doing and what's happening: Type sudo pip3 install [package]

• What's wrong / what should be happening instead:
  Following error message comes out when trying to install packages via pip.

Collecting [package]

None of these solutions work.

• Re-install pip
• Re-install WSL
• sudo pip3 install [package]
• pip3 install [package] with root account
• sudo -H pip3 install [package]
• pip install --user [package]

These commands works normally.

• python -V (3.6)
• pip3 --version (9.0.1)

Allow python in Windows Firewall. Link https://docs.microsoft.com/en-us/windows/wsl/troubleshooting

@Biswa96 How do I allow WSL Python in Windows Firewall? Is it possible to access WSL file from Windows?

[Biswa96]

Allow this path in Windows Firewall:

"C:\Users\username\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu18.04onWindows_79rhkp1fndgsc\LocalState\rootfs\usr\bin\python3.6"

The path may vary in Ubuntu versions from Windows Store. Explanation here: https://superuser.com/a/1325042/726810

Also check the /etc/resolv.conf file if any DNS server is present. If not then try to add, for example, echo nameserver 1.1.1.1 > /etc/resolv.conf (yes, by overwriting).

This could work

sudo apt -y purge python-pip
sudo python -m pip uninstall pip
sudo apt -y install python-pip
pip install --upgrade pip
echo "export PATH=\"${HOME}/.local/bin:$PATH\"" >>"${HOME}"/.bashrc

@Biswa96 I can't configure the path.

@MatheusRV pip install --upgrade pip gives me same error message 😢

[Biswa96]

Oh... Change the username to your user name in your PC

[hwooo]

That's my mistake...But result is same.

The cause was my Kaspersky app. If I turn off it, everything works well. I've raised this issue to Kaspersky.

sudo apt-get update
sudo apt-get upgrade
sudo apt install python3-pip
