After I upgraded to Quantal, evolution asked to create a new identity (as if the previous config and prefs were vanished).
When creating the calendar, it can't establish a connection with the server, and if I try to retrieve the calendars I receive an "http error: method not allowed"...
Please help!
My answer is not so different from Mar Warne's one. After a couple of reboots, my Personal Keyring started asking for google password, I could not say if because of Evolution, Web Accounts, or a Webapps related thing.
In any case, I tried with my google account password, but the dialog window continued to show up. Then I remembered I created a password for third party apps (2-step verication needed), and even if I disabled 2-step, some of my apps, such as Thunderbird or calendar clients still asks for the second password, don't know why.
So I tried this second one, and Evolution opened, showing my calendar multiple times (each time I created it, I suppose).
Just deleted the copies and all started to work again.
