Apt-从14升级到16之后，由于依赖关系问题而失败的命令

Question

apt-get升级的输出：

sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 gstreamer1.0-clutter : Depends: libcogl15 (>= 1.15.8) but it is not     installable
 libnux-4.0-0 : Depends: libsigc++-2.0-0c2a (>= 2.0.2) but it is not installable
 orage : Depends: libical1 (>= 1.0) but it is not installable
 python : Depends: python-minimal (= 2.7.5-5ubuntu3) but 2.7.11-1 is installed
 python-dev : Depends: python (= 2.7.11-1) but 2.7.5-5ubuntu3 is installed
              Depends: libpython-dev (= 2.7.11-1) but 2.7.5-5ubuntu3 is installed
E: Unmet dependencies. Try using -f.

Answer 1

有些软件包在14.04到16.04之间被淘汰，升级发行版时很常见。以下是你所做的：

如果您的问题包在16.04可用，则为-see。如果它们是，您可能希望sudo apt-get purge这些软件包，然后重新安装它们。您的包在16.04下可能有不同的依赖项，但是由于它们安装在14.04下面，所以它们有这个延迟列表。

-make确保您的sources.list只包含16.04的有效条目

-you可能希望从头开始重新安装16.04。像这样的“肮脏升级”并不总是100%的开箱即用。
