[Issue] No space left after fresh install - eviltoast

Hi, I just installed postmarketos on my OnePlus 6 and after an update of the packages (or install a new one), I get “no space left” errors. I followed the guide and flashed the partition like it’s written in it. Any reason that can cause this ?

OnePlus 6 with 128gb, using the prebuilt sxmo (sway) edge image.
