GS290 installation

after a month i have decided to give it a try again and install an older image for waydroid
however, now i can not download, or unzip the image
my system is out of space
when i do that:

rm -rf /var/lib/waydroid /home/.waydroid ~/waydroid ~/.share/waydroid ~/.local/share/applications/aydroid ~/.local/share/waydroid

i end up with 700 mb of space in system data, which is hardly sufficient to download and unzip the image
any ideas what i could clean up ?
