Thanks for your bugreport. The use-case with non-networked machines is something we do not document that well currently. Here is what you can do:
1. Ensure that the sources.list of the machines point only to the internal mirror (do not mix deb http://archive.ubuntu.com and deb http ://internal-mirror lines). The reason for this is that update-manager will not the be able to distinguish between 3rd party sources and inofficial mirrors. 2. Use the alternative CD (or DVD) to initiate the upgrade. "sudo sh /cdrom/cdromupgrade" should be fine. It then will tell you that it can not find a offical mirror in your sources.list and should offer you to simply rewrite all gutsy to hardy entries. Say yes here and it should work. You can use the same mechanism for dapper->hardy upgrades. Please let me know if you see issues with it. -- update-manager does not accept debian proxies https://bugs.launchpad.net/bugs/216907 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
