I had downloaded the source code of GNU octave and had installed it using
make install. However, the installation had some error, due to which it could not open the GUI on launching octave.
For this reason I wanted to un-install the package.
For un-installing, I opened the software center. There in installed packages list, I could see GNU octave enlisted. On clicking on remove button, nothing happens.
Hence I tried to uninstall the package from command prompt using
sudo apt-get remove octave sudo apt-get autoremove octave
Still octave did not disappear from
/usr/local/bin folder. So, I manually deleted it using:
sudo rm -rf /usr/local/bin/octave sudo rm -rf /usr/local/lib/octave
Now when I again go back to software center, GNU octave is still enlisted as installed software.
I want to install it again, properly. For which I want to completely remove the previous installation.
My questions are:
- What else is required to completely remove octave
- How to correctly install it so that I can use its GUI efficiently
Note: the octave version is 4.0.1 Ubuntu version - 16.04 LTS
