The problem of apt fix-broken install in Ubuntu

  • 772

When I need to use apt-get to install somethings.

$sudo apt-get install autoconf automake libtool curl make g++ unzip

make is already the newest version (4.1-9.1ubuntu1).
unzip is already the newest version (6.0-21ubuntu1).
unzip set to manually installed.
curl is already the newest version (7.58.0-2ubuntu3.8).
g++ is already the newest version (4:7.4.0-1ubuntu2.3).
g++ set to manually installed.
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 autoconf : Depends: m4 (>= 1.4.13)
 automake : Depends: autotools-dev (>= 20020320.1) but it is not going to be installed
 libtool : Depends: autotools-dev but it is not going to be installed
           Recommends: libltdl-dev but it is not going to be installed
 nvidia-cuda-toolkit : Depends: nvidia-cuda-dev (= 9.1.85-3ubuntu1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

After I got this error message, I tried to fix it.

However, when I typed 'sudo apt --fix-broken install', I got this error below.

$sudo apt --fix-broken install

In here, I already faced this problem many times about nvidia-cuda-dev. I installed cuda 10.2 version. But I don't know why it wanna use version 9? But I need this version(10.2), and I don't want to change it that I am afraid of my environment which will get wrong.

$nvcc --version

Sorry I am not familiar with setting of environment here. Is there any suggestion about this situation?

Thank you very much!

    The package nvidia-cuda-toolkit depends on nvidia-cuda-dev. nvidia-cuda-dev contains the file /usr/include/cublas.h which is also in package libcublas-dev so only one of those two packages can be installed at the same time, and currently that's libcublas-dev.

    So basically you can have either nvidia-cuda-toolkit or libcublas-dev but not both. Remove one of them.

    It seems libcublas-dev is made for another distro or Ubuntu version and not compatible with Ubuntu 18.04.
