When I use sudo apt-get update
I get following error.
E: Could not open file /var/lib/dpkg/status - open (2: No such file or directory)
E: The package lists or status file could not be parsed or opened.
Open the terminal,Ctrl + Alt + T,
$ sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
$ sudo apt-get update
Incase you get this error E: Lists directory /var/lib/apt/lists/partial is missing.
$ sudo mkdir /var/lib/apt/lists/partial
