Bug Description
Hardware: headless device (Axiomtek NA-330)
Connected to console port (RJ45) via minicom using 115200 8N1
In Ubuntu 14.04 LTS run do-release-upgrade (to Ubuntu 16.04.1 LTS)
At end, confirm reboot
No serial console after that (fortunately the network connection came up allowing ssh access)
Debugging/
/etc/
GRUB_
which was reflected in /boot/grub/grub.cfg
dmesg | grep tty produced
[ 0.000000] console [tty0] enabled
[ 1.612175] 00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[ 1.632768] 00:03: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a 16550A
systemctl enable console-
systemctl enable <email address hidden>
systemctl start console-
systemctl start <email address hidden>
Ctrl-A F in minicom returned the login prompt which hadn't worked previously
After the work-around the console port turned out to be ttyS0 so some of the above may not be necessary.
