recently on a update, dpkg tried to install a new kernel and /boot ran out of space.next boot it failed to find init image. so i rebooted, selected the previously good kernel, and tried to remove a few older ones.now it stays there. on gpkg. pstree shows dpkg (v 1.17.5) started runparts which started grub-mkconfig (grub v 2.02~beta2-9ubuntu1.5) which started grub-probe.and there it is for the last few hours.I already tried to kill the processes, remove an even older kernel from /boot so it has some free space, and then tried again. same thing. it hangs forever on grub-probe.anyone has any idea what is going on?
dpkg cannot remove old kernels. grub-probe halts
grub;dpkg
