Error with Fiware-Cygnus installation via yum

问题:

i am trying to install the Fireware Cygnus via yum

yum install cygnus-ngsi

But in the middle i got some erros.

Transaction Check Error:
  file /usr/cygnus/init.d/cygnus from install of cygnus-common-1.2.0-0.gbd4790e.x86_64 conflicts with file from package cygnus-0.13.0-0.g0c6765f.x86_64
-......

i checked the /usr directory but there is nothing with /cygnus/init.d and so on...

It is possible that there have been something before but who knows. I also tried to clean yum repo but the error still exists. Does anyone have an idea ?

回答1:

Try the following command in order to remove all Cygnus stuff:

sudo rpm -e -vv --allmatches --nodeps --noscripts --notriggers cygnus
sudo rpm -e -vv --allmatches --nodeps --noscripts --notriggers cygnus-ngsi

The first command will remove everything regarding Cygnus pre release 1.0.0, the second one will remove everything post release 1.0.0.

Hope this helps!

NOTE: from Cygnus 1.0.0 the code was split into cygnus-common, a library of common utils and classes for all Cygnus agents, and cygnus-ngsi, a NGSI specific agent (after that, other contributors have added more agents to Cygnus , such as cygnus-twitter by Universidad Politécnica de Valencia). That's why before release 1.0.0 Cygnus was installed as yum install cygnus and after 1.0.0 it is installed as yum install cygnus-ngsi.
