After experiencing problems with Garnet vm, I reinstalled it, after which the main menu items all disappeared. Since Garnet still would not run, I decided to remove it . However, I ran into the following problem:

/home/user # apt-get -f remove garnet-vm
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
/home/user # dpkg --configure -a
dpkg: failed to open package info file `/var/lib/dpkg/updates/0000' for reading: Input/output error

Any suggestions on how to run the above and get the menu back?

Thanks.
