How to install polymer iron and paper elements for Polymer 0.9 using bower? Tried using bower to install in a way similar to core-elements but fails. Migration guide doesn't provide any information on upgrading core/iron or paper elements.
bower install Polymer/iron-elements#^0.9.0
bower iron-elements#^0.9.0 not-cached git://github.com/Polymer/iron-elements.git#^0.9.0
bower iron-elements#^0.9.0 resolve git://github.com/Polymer/iron-elements.git#^0.9.0
bower iron-elements#^0.9.0 ECMDERR Failed to execute "git ls-remote --tags --heads git://github.com/Polymer/iron-elements.git", exit code of #128 fatal: remote error: Repository not found.

The new 0.9 elements are here.
You get them with bower this way:
bower install polymerelements/iron-ajax
I don't think there's an entire element collection ready yet, you should probably download every single needed element.
You can find more info about the new elements in the 0.9 release info:
Where did the elements go?
Not all elements have been ported to the current release, but we’re porting them as fast as we can. You can find work-in-progress versions of many elements in the PolymerElements GitHub organization.The elements are being reorganized into more consistent product lines, including:
Iron elements. Basic elements that don’t express a visual style. Most of the old core- elements are being renamed to iron-. Some former core- elements that implemented material design (such as core-toolbar, core-menu, core-header-panel) are being migrated to paper-.
Paper elements. Material design elements. All of the old paper- elements, plus a few of the old core- elements.
Neon elements. Animation elements.
These element sets will be launching with their own site sometime around the Polymer 1.0 timeframe. The new site will include API docs for the elements. If you want to get started with the work-in-progress versions, the individual repos are the best source for information about the elements right now.
You can also check out the community Road to Polymer project which is tracking the status of Polymer elements.
Also, you may find some valualble info in the Polymer Blog. Stay tuned!

Thanks Matteo. Adding to Matteo's answer we can install all available ported iron and paper elements for Polymer 0.9.0 using the following bower commands
bower install polymerelements/iron-elements
bower install polymerelements/paper-elements

for any elements installation, first go to element's page: https://elements.polymer-project.org/ and find the element you want. while inside the element's page, in the left hand side, there is 'Bower Command' section. just copy that and paste it in your shell/terminal/command prompt.

I had the same error as you reported, and was unable to install any elements using bower as proposed above. However, everything worked after running following command in my project folder:
git config --local url."https://".insteadOf "git://"
