My system: 32 bit, PIV 2.4 Ghz, 1GB RAM, No Graphic Card, Windows / Ubuntu dual boot system.

Two days ago, I did upgrade, which went smoothly. After restarting system, and doing login, I see only blank desktop, no Unity launcher or task bar, no gui, nothing. I can press Ctrl+Alt+T and open programs, but graphics looks very old.

I was trying solutions posted on this forums, one of command sudo apt-get install -f gave following error, which I was getting previously also.

Below error: 

Preconfiguring packages . . .
dpkg: error: parsing file '/var/lib/dpkg/available' near line 59
missing package name

A fatal error occurred.
Please report this as a bug and include the files.
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report. The upgrade has aborted.
Your original sources list was saved in 
/etc/apt/sources list.distUpgrade

System Error E: sub-process /usr/bin/dpkg/ returned an error code (2)

There are a few methods listed here to remedy the dpkg thing.

Only if the above does not help you, try this: run sudo cp /var/lib/dpkg/available /var/lib/dpkg/available.bak, and then sudo nano /var/lib/dpkg/available, remove the 59th line, save with Ctrl+O and ↵, and then exit with Ctrl+X - then try apt-get again. Then you should be able to reinstall Unity to restore the graphics.
