There may be something else going on the system causing u-u not detecting the difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871261 Title: package ufw 0.36-6 failed to install/upgrade: end of file on stdin at conffile prompt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1871261/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
