我是Ubuntu紐布，所以請耐心等待。
在嘗試卸載 Octave-3.2.4 時，我最終做了射頻在所有與八度相關的目錄和檔案上/usr/bin/在我安裝最新版本的 GNU Octave 之前。現在嘗試安裝 Octave 時，出現以下錯誤，我需要協助解決：
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.
我嘗試重新安裝 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
所有遺失的包都在主存儲庫中，因此
sudo apt-add-repository main
sudo apt-get update
也是multiverse個好主意
sudo apt-add-repository multiverse
sudo apt-get update
如果sudo apt-add-repository main和sudo apt-add-repository multiverse不起作用，請執行下列操作
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak- 打開Software & Updates
main啟動、universe和的條目multiverse
點選Close
透過以下方式刷新套件來源Reload
刪除你的自編譯冒險
cd octave-3.8.0
sudo make uninstall
octave透過再次安裝
sudo apt-get install --reinstall octave
請不要透過刪除以下文件來「刪除」軟體包/usr/bin
