I found the error. It appeared to be Firestarter that was blocking the connection to archive.ubuntu.com when "Block traffic from reserved addresses on public interfaces" was set (which seems like a bug to me - it doesn't happen in Feisty though). I tried several times so set and unset that setting and it was clearly related to being able to connect to the ubuntu server or not.
When I had found that out and unmarked that setting in Firestarter, update-manager was able to download the ReleaseAnnouncements file and the upgrade could start. -- update-manager becomes unresponsive because it cannot download ReleaseAnnouncement (needs sensible timeout) https://bugs.launchpad.net/bugs/109397 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
