E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
Setting up grub-pc (1.96+20080704-1) ...
Updating /boot/grub/grub.cfg ...
[: 212: ==: unexpected operator
[: 212: ==: unexpected operator
Found linux image: 
basename: missing operand
Try `basename --help' for more information.
dpkg: error processing grub-pc (--configure):
 subprocess post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of grub2:
 grub2 depends on grub-pc; however:
  Package grub-pc is not configured yet.
dpkg: error processing grub2 (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 grub-pc
 grub2

this is the bashism, the "==":
[: 212: ==: unexpected operator
