Users have different duplicity versions

  • 772

I've just installed the latest version of duplicity (0.7.18 at the time of writing) using these instructions to add the ppa then update.

I did this under my account which has sudo privileges and installed the package. Duplicity gives me the new version whether I become root or not.

james@box # duplicity --version
duplicity 0.7.18.1

However, when logged in as another non-sudoers user, duplicity shows the old version. I've tried logging out and back in again.

nasuser@box # duplicity --version
duplicity 0.7.14

With both users I get:

which duplicity
/usr/bin/duplicity

How do I get the non-root user(s) to see the updated version - 0.7.18.1?

And in general how does this kind of thing work? Does that /usr/bin/duplicity file really get called both times when the --version option is used, only referring to two different files elsewhere? Or is which not such a great tool as there are things it doesn't know about?

sudo apt duplicity 14.04

    As @N0rbert helpfully pointed out, pip had installed a local version of duplicity which the nasuser account was picking up and pip show duplicity showed this:

    /home/nasuser/.local/lib/python2.7/site-packages

    To remove this I used:

    pip uninstall duplicity

    Then duplicity --version returned the same thing for both users.
