我是 Ubuntu新手，所以请耐心等待。
在尝试卸载 octave-3.2.4 时，我最终这样做射频在所有与 Octave 相关的目录和文件中/usr/bin/在我安装最新版本的 GNU Octave 之前。现在尝试安装 Octave 时，我收到以下错误，需要帮助解决：
The following packages have unmet dependencies:
octave :
Depends: libarpack2 (>= 2.1) but it is not going to be installed
Depends: libfftw3-3 but it is not installable
Depends: liboctave3 (= 4.0.0-3ubuntu2~octave~precise5) but it is not going to be installed
Depends: libqscintilla2-8 but it is not installable
Depends: default-jre-headless but it is not installable
Recommends: pstoedit but it is not installable
E: Unable to correct problems, you have held broken packages.
我尝试重新安装 Octave 的命令：
wget ftp://ftp.gnu.org/gnu/octave/octave-3.8.0.tar.bz2
tar -xvf octave-3.8.0.tar.bz2
cd octave-3.8.0
sudo apt-get build-dep octave
./configure
make
sudo make install

答案1
所有缺失的软件包都在主存储库中，因此
sudo apt-add-repository main
sudo apt-get update
也是multiverse一个好主意
sudo apt-add-repository multiverse
sudo apt-get update
如果sudo apt-add-repository main不起作用sudo apt-add-repository multiverse，请执行以下操作
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak- 打开Software & Updates
激活 的条目
main，universe以及multiverse
点击Close
通过以下方式刷新包源Reload
删除你的自编译冒险
cd octave-3.8.0
sudo make uninstall
octave通过再次安装
sudo apt-get install --reinstall octave
请不要通过删除文件来“删除”软件包/usr/bin
