Analysis: This is caused by keyboard-configuration trying and failing to detect a keyboard.
It detects my USB keyboard using InterfaceClass 03, InterfaceSubClass 01, and InterfaceProtocol 01 in /sys/bus/usb/devices/ . It detects the built-in keyboard on my other computer using "AT Set" in /proc/bus/input/devices . However it does not detect the Surface Type Keyboard ('N: Name="Microsoft Surface Type Cover Keyboard"') in /proc/bus/input/devices . The problem is in the keyboard_present() function of line 36230 of /var/lib/dpkg/info/keyboard-configuration.config . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858090 Title: Surface Type Cover not detected by dpkg-reconfigure keyboard- configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/console-setup/+bug/1858090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
