I upgraded an OpenVZ VPS from an older Ubuntu release to 12.04LTS using the do-release-upgrade
command. Ever since, all of my apt-get
runs look something like this:
$ sudo apt-get upgrade

I am reasonably sure that something about the OpenVZ environment is causing this problem, likely the simfs /
and the lack of any disks (hd_
) in /dev
. But despite spending the last few hours reading all I can find on the /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
error, I still have this problem.
Worse comes to worse, I can restore from a backup that should be clean. But I would rather not do that, as it would mean some tricky BOINC-related footwork to resync with attached projects.
