Public bug reported:
Binary package hint: ifupdown
On boot up ifup fails to bring up alias interfaces. The interface is in a n
unknown state.
ifconfig

Try to bring up eth0:10
$ sudo ifup eth0:10
ifup: interface eth0:10 already configured
To manually resolve bring the interface down and then back up
$ sudo ifdown eth0:10
SIOCSIFFLAGS: Cannot assign requested address
$ sudo ifup eth0:10
SIOCSIFFLAGS: Cannot assign requested address
$ ifconfig eth0:10

I don't see anything in dmesg or any other logs. Let me know if there
is a log file you need for more information.
