I went to this site https://packages.debian.org/buster/amd6 ... e/download and downloaded the deb file, used pextract and opened and saved it as a dirrectory, changed the name of the bin application to lxappearance_old and changed the name of the desktop file *_old, then ran dir2pet from terminal and installed the old (lxde standard) lxappearance (now as lxappearance_old) and ran petget to install it like normal pet files.
Now I have the standard to LXDE appearance changer and icon theme exchanger. I put a link on the desktop.
Now when I run it i can change the icons fine.
A work around but that should do it for me.
