Bug when updating Anaconda-Navigator

[Clem Wang]

I just installed Anancoda on Ubuntu 20.04 with

bash /tmp/Anaconda3-2020.02-Linux-x86_64.sh

I launch anaconda-navigator.  It said I needed to update and when I did, I got an error.  The variable command is actually a list instead of string as can be seen in the source code

This is the trace:

anaconda-navigator

Traceback (most recent call last):

The problem is this code:

/home/clem/anaconda3/lib/python3.7/site-packages/anaconda_navigator/widgets/main_window.py

        command = [

            'navigator-updater',

            '--latest-version',

            version,

            '--prefix',

            prefix,

        ]

        as_admin = WIN and not is_root_writable

        return launch(

            prefix,

            command,

            leave_path_alone,

            package_name='anaconda-navigator-updater',

            root_prefix=root_prefix,

            non_conda=True,

            as_admin=as_admin,

        )

and launch() expects command to be a string.
