Ubuntu 14.04软件包依赖项问题

Question

Host: Ubuntu 14.04

When I executed a script, I got the following issue:

The following packages have unmet dependencies:
dh-python : Depends: python3:any (>= 3.3.2-2~)
lsb-release : Depends: python3 but it is not going to be installed

Depends: python3:any (>= 3.3.2-2~)
ubuntu-minimal : Depends: python3 but it is not going to be installed
              Depends: resolvconf

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I have entered apt-get -f install and executed the script again. However, it did not make any change.

The python version on my system is:

Python 2.7.6 (default, Jun 22 2015, 17:58:13)

Answer 1

Python 3 is the key here. You are using Python 2.

So, I highly recommend using Anaconda for your purposes. It will allow you to switch between Python2 and Python3

In your browser download the Anaconda installer for Linux , then in your terminal window type the following, replacing the file path and name with the path and name of your downloaded install file. (There is also a gui installer that sets up a PATH entry)

Follow the prompts on the installer screens, and if unsure about any setting, simply accept the defaults, as they can all be changed later:

bash ~/Downloads/Anaconda-2.3.0-Linux-x86_64.sh

Now add conda to your path

PATH=$PATH:$HOME/anaconda/bin

*replace the path with the correct path to anaconda/bin wherever it lives on your machine

Now create an environment that uses python3

conda create --name test python=3

Activate your environment

source activate test

You will see an environment (test) in front of your command prompt. Test can be renamed to suit your needs.

Verify:

python --version
