Title: Repeating "can't open /dev/ttyX: No such device or address" messages during installation Status in Ubuntu on IBM z Systems: Confirmed Status in console-setup package in Ubuntu: Incomplete Status in linux package in Ubuntu: Confirmed Bug description: [Impact] console-setup continuously tries to open /dev/tty[1-6] on s390x, when such consoles do not exist on s390x. This can be seen on boot in the output from the initramfs, and during the installer. [Cause] It seems to me that the postinst of the console-setup is incorrect for s390, since on s390 Linux tty[1-6] do not exist in any modes (LPAR, z/VM, KVM) [Solution] I do not know what ACTIVE_CONSOLES should be set as, my guess is to set it to... "guess". Usually it should be slcp, but that depends on which consoles are configured/activated in the given KVM. [Testcase] On boot, scroll all the messages and makesure there are no error messages about inability to open /dev/tty* [Original Bug Report] During the installation (z/VM guest and KVM virtual machine) of Ubuntu Server 16.04.1 (and 16.04.2) repeating messages of the form: " Select and install software ... 10% can't open /dev/tty4: No such device or address can't open /dev/tty2: No such device or address can't open /dev/tty3: No such device or address can't open /dev/tty4: No such device or address can't open /dev/tty2: No such device or address can't open /dev/tty3: No such device or address can't open /dev/tty2: No such device or address can't open /dev/tty4: No such device or address can't open /dev/tty4: No such device or address can't open /dev/tty3: No such device or address can't open /dev/tty2: No such device or address can't open /dev/tty2: No such device or address can't open /dev/tty3: No such device or address ... 20% can't open /dev/tty4: No such device or address can't open /dev/tty2: No such device or address can't open /dev/tty3: No such device or address ... 30%... 40% can't open /dev/tty3: No such device or address can't open /dev/tty4: No such device or address can't open /dev/tty2: No such device or address ... 50% can't open /dev/tty3: No such device or address can't open /dev/tty4: No such device or address can't open /dev/tty2: No such device or address ... 60% can't open /dev/tty2: No such device or address can't open /dev/tty3: No such device or address can't open /dev/tty4: No such device or address can't open /dev/tty2: No such device or address ...
