我正在尝试安装 nodejs，但是收到以下错误消息：
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
nodejs : Depends: python-minimal but it is not installable
E: Unable to correct problems, you have held broken packages.
然后尝试安装 python-minimal 时失败，并显示 python2-minimal 已替换。Python2-minimal 已经是最新版本
sudo apt-get -f install
返回
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
命令：
dpkg --get-selections | grep hold
未列出任何输出。
有什么建议么？
