System: Lenovo ThinkPad x121e (intel), LVM based setup with separate root, var, and home filesystem. var getting somewhat tight due to the packages downloaded and kept for the upgrade.
During the upgrade from 13.10 to 14.04, the upgrade process failed to continue. From output and processes around, it seems to be hanging in update-grub. The last action observed was logged as "installed dbus-x11".
It's been stuck since hours - how to proceed?
/var/lib/dpkg
is locked
/var/cache/debconf/config.dat
is locked (hanging update-grub process)
- HUP the update-grub and hope for upgrade to continue, run update-grub later on manually
- HUP the upgrade, and hope it is either reentrant or successful at reestablishing prior conditions.
- if all else fails, it'll take longer...
Due to filesystem sizes on the Notebook, I'd rather avoid the full install - reinstall packages - revert to backup procedure, even though the result would be clean and preferrable. It's the obvious if-all-else-fails fallback, but I'm also curious on how graceful the update process can be salvaged.
Any ideas?
