Something's up with the installer itself. I can reproduce the issue on Lucid which is older than ttylinux kernel. To confirm the -curses and keyboard input works correctly, I appended BOOT_DEBUG=3 (during the blind typing steps) after console=ttyS0
Then on the serial console page, I get a proper shell serial0 console + debugshell just booted + [ 3 -gt 2 ] + echo This is a debug shell (just booted). This is a debug shell (just booted). + sh BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) Enter 'help' for a list of built-in commands. sh: can't access tty; job control turned off ~ # echo "hello" hello ~ # uname -a Linux (none) 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:12:07 UTC 2012 x86_64 unknown -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1427829 Title: enter doesn't work on iso install over serial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1427829/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
