I do also having a fpcupdeluxe bug, i have not read yet your link, i do use windows, having laz 2.2.2 via fpcupd installed, downloaded newest fpcupd, set [stable] for compiler and ide, hit the setup/update button, it begin its job the normal way, installed a million lines of unreadable fast things, after it was finished... i was disappointed. It did not updated like i assumed to laz 2.2.4 it just re-installed everything like it was before.
