软件中心的“安装状态”选项卡中显示的应用程序是否是用户特定的？

根据我找到的代码，软件中心的“安装状态”选项卡中显示的应用程序是基于用户的“/var/lib/dpkg/status”文件中的信息来确定的。因此，这些安装状态是特定于每个用户的。下面是一些代码示例，您可以查看“/var/lib/dpkg/status”文件并获取有关每个软件包的信息：

def get_package_status(package_name, user):
    """
    Get installation status of a package for a specific user.
    Args:
        package_name (str): name of the package
        user (str): username of the user
    Returns:
        (bool) True if package is installed, False otherwise
    """
    try:
        with open(f'/var/lib/dpkg/status', 'r') as status_file:
            for line in status_file:
                if line.startswith('Package:'):
                    current_package = line.split(' ')[1].strip()
                elif 'Status:' in line and current_package == package_name:
                    status_info = line.split(' ')[2]

                    # Check if package is installed for the specific user
                    if f'/{user}/' in status_info:
                        return True
            return False
    except FileNotFoundError:
        return False

# Example usage
is_installed = get_package_status('firefox', 'john')
print(is_installed)
