Ok, so there might be two issues. One still with upgrades and

I've got no knowledge about PXE, but you mentioned several installs, so
could it be that you accidentally mix two installs. This at least could
happen, if you've got wrong bootloader entries, when booting from a
normal disk install, perhaps PXE settings also allow to boot the kernel
from another install.
