maas-deployer failed on already install maas

[Narinder Gupta]

I am seeing this issue when i am trying to deploy maas on orange pod2 again. MAAS is up and running but when i tried to redploy it then getting the below issue. Looks like something is fishy in this environment.

+ sudo maas-deployer -c deployment.yaml -d --force
Traceback (most recent call last):

Hi Narinder, first comment i'd make which is not directly related is that you should not run maas-deployer as root (there is no need to). Second, can you tell me what version of python-maas-client you have installed? (the above would indicate that somehow you do not have this installed anymore yet it is a package dependency of maas-deployer).

I tried all means removing the maas-deployer and python-maas-client and other components. And still finding the same issue only on this server. I have two other systems where issue was not seen. I can not reimage this server as this is main CI server.

here is pytthon maas-client.

Today i got another unit exhibiting the same behavior so virus is spreading before it affects the real customers. We need to understand the issue and find the root cause.

Hi Narinder, can I ask you for the following:

  * please upgrade to the latest maas client
  * confirm that the issue still exists with the latest packages (currently 1.9.1+bzr4543-0ubuntu1~trusty1)
  * provide the output of dpkg -l| grep maas

[Narinder Gupta (narindergupta)]

i still can see same issue with latest maas client as well.
any maas commands can not run simple export also failing.

jenkins@jumphost2:~$ maas maas nodes list
/usr/bin/python: No module named maas_client; 'maascli' is a package and cannot be directly executed
jenkins@jumphost2:~$

jenkins@jumphost2:~$ dpkg -l | grep maas
ii maas-cli 1.9.1+bzr4543-0ubuntu1~trusty1 all MAAS command line API tool
ii maas-deployer 0.0.6-0ubuntu0.1 all MAAS cluster deployment tool.
ii python-maas-client 1.9.1+bzr4543-0ubuntu1~trusty1 all MAAS python API client

I think something is FUBAR with the python-maas-client installation here. I think purging and reinstalling may fix your problem.

[Narinder Gupta (narindergupta)]

still finding the same issue after doing the purge and reinstall.

[Narinder Gupta (narindergupta)]

finally got the problem when we pip install google-api-python-client then it creates an path entry of /usr/local/lib/python2.7/dist-packages/googleapiclient
so /usr/local/lib/python2.7/dist-packages/ is before /usr/lib/python2.7/dist-packages/ in path which casues the issue. After removing the google-api-python-client it worked fine but I think it has to be fixed in package also so in case of mutiple option in path it should able to figure it out.
