subiquity on UC18 says it is UC16 (and 18 too)

[Ian Johnson]

I was fiddling with some things on my rpi4 UC18 install with the released images from cdimage after running console-conf and after a reboot I did not have working networking. This caused console-conf to display the expected message about "You cannot log in until the system has an IP address.", but it also confusingly claimed the device was a UC16 device:

[ OK ] Started Update UTMP about System Runlevel Changes.

Ubuntu Core 16 on <no ip address> (ttyS0)

You cannot log in until the system has an IP address.
(Is there supposed to be a DHCP server running on your network?)
Ubuntu Core 18 on <no ip address> (ttyS0)

You cannot log in until the system has an IP address. (Is there
supposed to be a DHCP server running on your network?)

This was taken from the serial getty I don't know if subiquity displays the same message about UC16 on the display as well, but obviously this is not a UC16 device so it should not be saying Ubuntu Core 16.

Fwiw, this is in write_login_details_standalone():
"""
    if len(ips) == 0:
        tty_name = os.ttyname(0)[5:]
        print("Ubuntu Core 16 on <no ip address> ({})".format(tty_name))
        print()
""""

This also happened in amd64 uc18, on the VGA console, apparently when a request for an IP address failed.

Just noticed the same here when playing with appliances, this really should get fixed...

I am also facing this problem when I tried to bring up ubuntu core on imx8(arm64) based board.
