Please note, that you can't directly upgrade from postmarketOS "busybox-extras" to the upstreamed version.
To upgrade properly, do the following:
* delete your self-compiled busybox* packages:
`sudo rm ~/.local/var/pmbootstrap/packages/armhf/busybox*`
* zap all your armhf chroots with:
`./pmbootstrap.py zap`
