An I/O error from dpkg while unpacking a .deb sounds like either a broken
package file, or a memory
or hard disk error.
Could you do this and report if things works after that?
open terminal window
run "sudo apt-get clean"
Then run update-manager again, click on "Check" to refresh the package
lists, and then upgrade?
** Changed in: update-manager (Ubuntu)
Status: New => Incomplete
