You are upgrading from version 3.2.2 of base-passwd which had a nasty |

bug: it swapped the uid and gid of local accounts. If you have not |

fixed this problem manually I can undo the changes by restoring your |

previous passwd file from the backup /etc/passwd.org. |

update-passwd has found some differences between your system accounts |
|
and the current Debian defaults. It is advisable to allow update-passwd |
|
to change your system; without those changes some packages might not work |

correctly. For more documentation on the Debian account policies, please |

see /usr/share/doc/base-passwd/README. |

It is highly recommended that you allow update-passwd to make these changes |

(a backup file of modified files is made with the extension .org so you can |

always restore the current settings). |
