Re: Decommision Ubuntu 16.04 images on ODL Jenkins and update to Ubuntu 18.04 images on releng/builder repo.
Ubuntu 16.04 is going to be EOL by April 2021 and these images would no longer be supported on our infrastructure to receive updates/new builds. The version of python 2.7 that is available on Ubuntu 16.04 is already EOL and does not works with some of the tox/verify jobs. Therefore, it's required to update existing jobs to use the Ubuntu 18.04 image and decommission Ubuntu 16.04 images.
The below Ubuntu 16.04 images are in use in the releng/builder repo CSIT jobs:
"ZZCI - Ubuntu 16.04 - mininet-ovs-25 - x86_64 - 20200813-044931.688" (Label: ubuntu1604-mininet-ovs-25-1c-4g)
"ZZCI - Ubuntu 16.04 - mininet-ovs-28 - x86_64 - 20200813-051640.743" (Label: ubuntu1604-mininet-ovs-28-1c-4g)
Which needs to be updated to:
"ZZCI - Ubuntu 18.04 - docker - x86_64 - 20200901-040308.994" (Label: ubuntu1804-docker-4c-4g)
"ZZCI - Ubuntu 18.04 - docker - x86_64 - 20200901-040308.994" (Label: ubuntu1804-docker-2c-2g)
"ZZCI - Ubuntu 18.04 - mininet-ovs-25 - x86_64 - 20200813-035525.790" (Label: ubuntu1804-mininet-ovs-28-1c-4g)
Note: To test the CSIT jobs with the Ubuntu 18.04 images, update the image labels on the JJB/project before pushing the job to ODL Jenkins sandbox.
Packer build jobs for Ubuntu 16.04 image would be removed:
