        This package appears to be installed incorrectly.

        It should be installed as "PackagesManager", but seems to be installed
        as "%s".

        To fix the issue, please:

        1. Open the "Preferences" menu
        2. Select "Browse Packages\u2026"

        installed_dir,

        It appears you have PackagesManager installed as both a
        .sublime-package file and a directory inside of the Packages folder.

        To fix this issue, please:

        1. Open the "Preferences" menu
        2. Select "Browse Packages\u2026"
        3. Delete the folder "PackagesManager"
        4. Restart Sublime Text

                Your system's locale is set to a value that can not handle
                non-ASCII characters. PackagesManager can not properly work
                unless this is fixed.

                On Linux, please reference your distribution's docs for
                information on properly setting the LANG and LC_CTYPE
                environmental variables. As a temporary work-around, you can
                launch Sublime Text from the terminal with:
