[Solved] OpenContrail Web UI login error "Install feature package"

Try following steps if you are installing from source code using contrail-installer.

I found this issue with CONTRAIL_BRANCH R2.1, Ubuntu 12.04.4, contrail-installer master branch (commit id:600d4db0ef99f570b475e5e5241ff3c746987acd)
and resolved by steps below.

1)
Goto
#cd /opt/stack/contrail/contrail-web-core

2)
Run
#make dev-env REPO=webController

3)
Restart the servers

#screen -x
Goto "ui-jobs" and "ui-webs" screen tabs and restart the servers (node webServerStart.js and node jobServerStart.js)

OR

#cd /home/saju/contrail-installer
#./contrail.sh stop
#./contrail.sh start

4)
Open Web UI
