I tried to remove flatpak and it was not found. Hence no installation of
related libraries. The upgrade from 9 to 10 to 11 may have caused this
error to creep in.

I then installed flatpak OK with font errors:

It originally was Debian 8 which used backports then was upgraded to
Debian 9 then 10 then 11. Errors only occurred last week when I upgraded
from 9 to 10 then 11.
