Comment 3 for bug 1645641

I guess this has to do with the dependency on contrail-web-core package.

contrail-web-core_3.1.1.0-45_amd64.de should depend on nodejs (>= 0.10.35-1contrail1),
but it actually depends on nodejs (>= 0.8.15-1contrail1).

So, nodejs package is not updated during upgrade.

Upgrading nodejs package resolved the issue.

Even running the following fab tasks instead of apt-get resolves the issue too.

fab uninstall_webui
fab install_webui
fab setup_webui

Please fix this.
