尝试从 ubuntu 存储库安装最新的 minitube-ubuntu 时：
The following packages have unmet dependencies:
minitube-ubuntu: Depends: libc6 (>= 2.14) but 2.17-0ubuntu5 is to be installed
Depends: libgcc1 (>= 1:4.1.1) but 1:4.7.3-1ubuntu1 is to be installed
Depends: libphonon4 (>= 4:4.2.0) but 4:4.7.0really4.6.0-0ubuntu2 is to be installed
Depends: libqt4-dbus (>= 4:4.5.3) but 4:4.8.4+dfsg-0ubuntu9.1 is to be installed
Depends: libqt4-network (>= 4:4.5.3) but 4:4.8.4+dfsg-0ubuntu9.1 is to be installed
Depends: libqt4-sql (>= 4:4.5.3) but 4:4.8.4+dfsg-0ubuntu9.1 is to be installed
Depends: libqtcore4 (>= 4:4.8.0) but 4:4.8.4+dfsg-0ubuntu9.1 is to be installed
Depends: libqtgui4 (>= 4:4.8.0) but 4:4.8.4+dfsg-0ubuntu9.1 is to be installed
Depends: libstdc++6 (>= 4.2.1) but 4.7.3-1ubuntu1 is to be installed
Depends: phonon-backend-gstreamer but it is not going to be installed
在我看来 2.17 >= 2.14，但也许数学在类 Unix 系统上有所不同？:( 我该怎么做才能解决这些依赖关系？
根据建议，我尝试安装 phonon-backend-gstreamer
sudo apt-get install phonon-backend-gstreamer
[sudo] password for gilnaa:

Package phonon-backend-gstreamer is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

答案1
当尝试使用 安装软件包时apt-get，如果依赖项未得到满足，它会列出依赖项集，包括任何需要更新的依赖项（看起来您有一些待安装的更新）。您的问题是phonon-backend-gstreamer无法安装。您可以sudo apt-get install phonon-backend-gstreamer单独运行，以查看无法安装的原因。
