Traceback after going through "Identify keyboard"

[Brian Murray]

I was installing with subiquity version 19.10.1 and received a Traceback after going through the "Identify Keyboard" steps and then pressing up arrow.

Dimitri indicates that pressing "Tab" would have avoided this.

Well pressing "Tab" also caused the same Traceback.

This is fixed in the stable/ubuntu-19.10 channel now. If you boot an eoan daily (up to and including 20191014, the next one will contain the fix), it will offer to update you to 19.10.2 which should then be able to complete the install.
