Not sure if this is your problem Martin, but this could happen if you are updating grub-pc, or running update-grub, as a user with a Kerberized NFS home directory. If you are anywhere in the home directory, and use sudo to run those commands, then you will get errors like the above (if local root is not given root privileges on the NFS mount).
I just encountered this bug myself and it prevented grub-pc from updating. This shouldn't be a show-stopper: grub-pc should report that grub was installed correctly and just print a warning that it couldn't cd back to the original directory, as other packages seem to do. For example, openoffice.org-emailmerge didn't fail, but just said this: Setting up openoffice.org-emailmerge (1:3.2.0-7ubuntu4.2) ... cd: 84: can't cd to /home/yozen and continued. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/673438 Title: update-grub: cannot restore the original directory -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
