Thanks Brian for your quick answer! Not sure why you fixed it as invalid. I guess it's a technical matter.
Though I had disabled all ppa, I was not able to upgrade to saucy. Then following your instructions I removed xorg-edgers-ppa, but the problem remains. I have been using ubuntu for years, and have sufferd many issues, but I've never found myself being "rejected" to upgrade. It's not critical for me, I can keep in raring. It's just to share a problem that may indicate different issues. And I thought it could be quite serious that the upgrader core provides not clear solution and lets you off. thkx again -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1248692 Title: just trying to upgrade 13.04 -> 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1248692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
