Metadata is Incorrect in Ubuntu Font Set

[Harry W. Haines, III]

This has been going on for quite a while and still cannot understand why it has not been corrected.
Metadata in Ubuntu Medium, Ubuntu Light and Ubuntu Thin does not follow standard convention.

Abbreviated output of fc-list | grep Ubuntu (showing the problematic fonts)

Ubuntu-L.ttf: Ubuntu,Ubuntu Light:style=Light,Regular
Ubuntu-LI.ttf:Ubuntu,Ubuntu Light:style=Light Italic,Italic
Ubuntu-M.ttf: Ubuntu,Ubuntu Light:style=Medium,Bold
Ubuntu-MI.ttf: Ubuntu,Ubuntu Light:style=Medium Italic,Bold Italic
Ubuntu-Th.ttf: Ubuntu,Ubuntu Thin:style=Thin,Regular

But fc-list output should be:
Ubuntu-L.ttf: Ubuntu Light:style=Regular
Ubuntu-LI.ttf: Ubuntu Light:style=Italic
Ubuntu-M.ttf: Ubuntu Medium:style=Regular
Ubuntu-MI.ttf: Ubuntu Medium:style=Italic
Ubuntu-Th.ttf: Ubuntu Thin:style=Regular

This affects Bionic, Cosmic, Dingo and Eoan and distributions based on them. Very large set.
Applications affected, Libreoffice, Scribus, Inkscape, Pinta and others. Some cannot even see Medium or Light fonts.

I have attached a set of corrected fonts for review. A fix is possible.

Please see the attached Libreoffice screen shot of the corrected fonts.

Status changed to 'Confirmed' because the bug affects multiple users.
