A problem with licenses

[Tommi Höynälänmaa]

I have published some software under GNU GPL and LGPL. However, when I 
open the Debian packages with Ubuntu Software Installation (18.04) the 
application claims that the software is proprietary. How can I fix this?

The relevant packages are:

   http://www.iki.fi/tohoyn/theme-d/theme-d_1.1.0_amd64.deb
http://www.iki.fi/tohoyn/theme-d/th-scheme-utilities_1.4.1_all.deb
   http://www.iki.fi/tohoyn/theme-d/libthemedsupport_1.1_amd64.deb
