Eduroam also just stopped working for me. I heard local admins "reconfigured wifi network", and now when I connect, I get "self-signed certificate" errors.
To solve this, I had to replace the old local certificate (LITNET_CA.crt for me) to the AddTrustExternalCARoot.crt.

And I'm not even on Ubuntu. I use ArchLinux.
