Indeed, using kko's recipe I could *sometimes* reproduce it on Dapper, and not at all on Feisty. But since Feisty does not have any changes wrt. ticket handling compared to dapper and because I cannot reliably reproduce it in Dapper either I guess it still affects Feisty in some way.
However, I could log into a different console/pty without any problem in every case, so it never locked me out completely. Did that happen to anyone? ** Changed in: sudo (Ubuntu) Importance: Wishlist => Medium Status: Needs Info => Confirmed -- "sudo -k" fails when timestamp is in the future https://launchpad.net/bugs/43233 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
