[Bug 1766247] [NEW] Invalid hostname when put FQDN on "do not configure network"

[Neyder]

Public bug reported:

I was trying QA testing for lubuntu in:

http://iso.qa.ubuntu.com/qatracker/milestones/389/builds/170809/testcases/1700/results

"Alternate Install (No Network) in Lubuntu Alternate i386 in Bionic
Daily"

when i put FQDN hostname after selecting "Do not configure network at
this time" show red screen:

Invalid hostname
The name "host.sub.domain.tld" is invalid.
...

If i go back and put only hostname it works.

It only happens with this network configuration, manual or
dhcp/autoconfig allows FQDN names.
