So mount is blocked (that is, it is refusing to respond to the kernel). This probably means that the device it's trying to unmount is not responding. This would also explain your issue with grub-update (and os-prober). os-prober will temporarily mount all disk devices (e.g. all partitions) on your system in order to scan them for other operating systems. If one of those devices is causing mount to block, then that will result in os-prober hanging. You should investigate which device is causing problems (os-prober will log to syslog, which may give you an idea into how far it got before hanging). > and then it reboots. > > For me upgrade problem, it comes from the update-grub, if I run it I can > the same > > Generating grub configuration file ... > Found background image: /usr/share/images/desktop-base/desktop-grub.png > Found linux image: /boot/vmlinuz-3.2.0-3-amd64 > Found initrd image: /boot/initrd.img-3.2.0-3-amd64 > No volume groups found > > I will try to purge and reinstall grub.
