Not quite sure what’s going on there (source vs. binary package difference?).

Not quite sure what’s going on there (source vs. binary package difference?).

I must have had something cached locally when I tested, thanks for the catch on this. Not knowing what else we will encounter between a source build on 24.05 vs on master, I am going to just revert to the deb-based packaging that we were doing with armcord/legcord already on 24.05 and let it be retired when 24.05 goes out of support.
