Ubuntu: all packages removed with apt-get remove, how to recover



Question:

I was trying to uninstall python2.7 package using apt-get remove, but it seems all packages are removed. I think I tried with "sudo apt-get remove python2.7". After reboot left pane is not coming on the desktop.

I tried running apt-get update from single user mode, but it is failing with following errors.

  W: A error occurred during signature verification. The repository is not updated and the previous index files will be used.

Ubuntu 12.04.2 LTS(precise) 64-bit is running in my HP ProBook 4420s laptop.

Can you help me to restore my laptop with "Ubuntu 12.04.2 LTS(precise) 64-bit".
