[solved] "cerbot certificates" throws an exception

rubashka55 · 2020-05-01 05:28:05

My OS is up to date, as well as the package certbot.

$ sudo certbot certificates
Traceback (most recent call last):
  File "/usr/bin/certbot", line 11, in <module>
    load_entry_point('certbot==1.3.0', 'console_scripts', 'certbot')()
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 490, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 2854, in load_entry_point
    return ep.load()
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 2445, in load
    return self.resolve()
[............]
  File "/usr/lib/python3.8/site-packages/cryptography/hazmat/primitives/constant_time.py", line 11, in <module>
    from cryptography.hazmat.bindings._constant_time import lib
ImportError: libffi.so.6: cannot open shared object file: No such file or directory

And

sudo find / -iname *libffi.so*
/usr/lib/libffi.so.7.1.0
/usr/lib/libffi.so.7
/usr/lib/libffi.so

Why does libffi.so.6 not exist? Where to get it? Why is certbot not up to date?

How to fix it?

It doesn't exist because it's obsolete. You don't get it, you rebuild things against the new version.

Can you open a python terminal and do 'from cryptography.hazmat.bindings._constant_time import lib' successfully?

No, the same exception

I'd reinstalled certbot before posting my question. Why wasn't it installed with the new version?

This sort of breakage is often caused by installing python libraries system-wide using pip. Have you done that?

# pip list

What do you mean? According to the output you are running certbot 1.3.0, which is the latest version available in the Arch repos.

Nothing packaged in the Arch repos depends on the old version of libffi, so this is either caused by a partial update (which you refute) or something installed from a third party (i.e. pypi via pip)

Also, please do not bump your thread unnecessarily. If you are the last person to post something, and you have more to add, use the edit button to append the additional information.

What version of python-cffi?

rubashka55 · 2020-05-01 14:21:31

$ sudo pacman -S python-cffi
warning: python-cffi-1.14.0-1 is up to date -- reinstalling

Scimmia · 2020-05-01 14:23:35

That's your problem, pkgrel 2 is the latest, and is the version rebuilt for the libffi soname bump. https://www.archlinux.org/packages/extr … thon-cffi/

What mirror are you using?

Which mirror are you using (check which is at the top of the list in /etc/pacman.d/mirrorlist), it appears to be out of date.

This mirror:

http://mirror.nus.edu.sg/archlinux/$repo/os/$arch

it's out of sync, yes. Why did it become out of sync?

Looks like it hasn't synced since mid-March. There could be any number of reasons for it stopping. The important thing is that you need to pick an alternative mirror and update your system.
