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
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
