Thanks schroeder!! Changing the line you pointed out to just return True made my install/upgrade to continue.
The update-manager downloads the upgrade scripts and puts them in /tmp. What I did was to go into the directory /tmp/tmpwArERK/ (i assume the exact name will differ from machine to machine...) and change the line below in 'DistUpgradeControler.py': Before change: # ask the user if he wants to do the changes res = self._view.confirmChanges(_("Do you want to start the upgrade?"), changes, self.cache.requiredDownload) return res After change: #res = self._view.confirmChanges(_("Do you want to start the upgrade?"), # changes, # self.cache.requiredDownload) return True #res I then executed just the gutsy upgrade script (running update-manager again will not work since it downloads the script again): sudo /usr/bin/python /tmp/tmpwArERK/gutsy --have-prerequists --with-network -- Upgrade to 7.10 hangs at "Modifying the software channels/Checking package manager" https://bugs.launchpad.net/bugs/152296 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
