Python-pip install (upstream) error?

[lplcleary]

I am trying to install python-pip on my manjaro system. This is so I can use pip to install other python packages. I am seeing the following error which, to me, looks like it may be upstream:

:: Proceed with installation? [Y/n] y
(19/19) checking keys in keyring                         [##############################] 100%

error: python-distlib: signature from "Felix Yan <felixonmars@archlinux.org>" is invalid

Do you want to delete it? [Y/n] y
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.

The error occurs if I choose not to delete that file as well. I am somewhat new to the workflow of aur packages, if this is an upstream error, what’s my course of action? If it’s not, any ideas why I might be seeing this error?

I am running a clean version of manjaro in a virtual machine.

Welcome to the Forum!

Follow the instructions from the following tutorial to solve your issue:

Update or package installation returns “error: failed to commit transaction (invalid or corrupted package)”

I can’t install or update a package because I get (something like) this: error: failed to commit transaction (invalid or corrupted package) Errors occurred, no packages were upgraded. Why is this happening? The package manager, pacman , has detected a malformed or incomplete package. By design it will not install the broken package. This is a design feature, not a flaw - you dont want to install corrupted files. This issue normally happens because the process was interrupted (for example …

Remember to not install python modules using sudo pip as it will - long term - cause conflicting files during system sync.

All common python modules are available using pacman

pacman -S python-<module-name>

Use virtual environments which also removes the necessity for a system wide python-pip.

This did not solve the issue. To clarify the package that’s causing the issue is a dependency of the arch user repository for python-pip (Arch Linux - python-pip 20.3.4-1 (any)). So clearing my cached packages does not make the install work.

You are confusing AUR with the official Arch repo - and there is no issues installing the python-pip from Manjaro repo.

Thanks! Didn’t know that. This solved the issue.

This does not work for me. This is the command I’m running when I see the error I posted about above.
