perfSONAR User Q&A and Other Discussion

["Kim, DongInn" <>]

Hi,

I tried to install perfSonar-core on ubuntu-16.04 with the installation instruction, http://docs.perfsonar.net/install_debian.html

but I have got the following issue of not being able to meet the dependency of python-djangorestframework-extensions.

Is there a way to resolve this dependency issue?

root@cdc:/etc/apt/sources.list.d# apt-get install perfsonar-core

Reading package lists... Done

Building dependency tree

Reading state information... Done

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:

The following packages have unmet dependencies:

 perfsonar-core : Depends: esmond but it is not going to be installed

E: Unable to correct problems, you have held broken packages.

The following information may help to resolve the situation:

The following packages have unmet dependencies:

 esmond : Depends: cassandra but it is not going to be installed

          Depends: python-support but it is not installable

          Depends: python-djangorestframework-extensions (>= 0.2.8) but it is not installable

E: Unable to correct problems, you have held broken packages.

It seems that cassandra has the dependency of python-support and python-djangorestframework-extensions.

This is the list of djangorestframework packages that I could find in the ubuntu-16.04 repo.
