When I tried to upgrade to Edgy, faced with the same problem. Then I installed 'python vte' using 'Synaptic' - took only 1.5 hours, now I have Edgy on my machine!
But I beleve, if update process is dependent on 'python vte' it should look for it, rather than throwing an error. Note: I installed Breezy, then upgraded to Dapper and from there I upgraded to Edgy. -- update-manager in dapper needs to depend on python-vte (was: "can't find DistUpgradeViewGtk" when upgrading dapper->edgy) https://launchpad.net/bugs/67999 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
