"-DAMA-Ubuntu Condensed-regular-normal-normal-*-29-*-*-*-*-0-iso10646-1"

So... not the right family and it's "condensed", for some reason.

For comparison,

(set-face-attribute 'default nil :height 110 :family "Ubuntu")

results in

"-DAMA-Ubuntu-regular-normal-normal-*-29-*-*-*-*-0-iso10646-1"

And by default (without any set-face-attribute calls),

(face-font 'default) evaluates to

"-DAMA-Ubuntu Mono-regular-normal-normal-*-35-*-*-*-m-0-iso10646-1"

Current emacs-28 returns

"-PfEd-Inconsolata_dz-normal-normal-normal-*-29-*-*-*-m-0-iso10646-1"

Regarding "version of Emacs that predates", I wasn't sure which commit 
to pick exactly, but 756b8a5f1bd28aeadc804 also returns that value, and 
doesn't have the described problem.

It doesn't look as narrow, and (face-font 'default) evaluates to

"-PfEd-Inconsolata_dz-medium-normal-normal-*-32-*-*-*-m-0-iso10646-1"
