Hi again,
Dou you have some locally-installed harfbuzz lingering around somewhere in the library search path?(i.e. /usr/local) This sounds like a locally-installed harfbuzz without graphite2 support.
And if that is the case this is no bug. The packages can't only know what is in the official harfbuzz packages
ii libgraphite2-3 1.3.14-1 [...] ii libharfbuzz-icu0 2.7.4-1 ii libharfbuzz0b 2.7.4-1 And those DO have that as they ARE built with graphite2 support. Regards, Rene
