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)
/var/lib/dpkg/available
? - you can usecat -n /var/lib/dpkg/available
to find it.sudo cp /var/lib/dpkg/available /var/lib/dpkg/available.bak
, and thensudo nano /var/lib/dpkg/available
, remove the 59th line, save with Ctrl+O and Enter, and then exit with Ctrl+X - then tryapt-get
again. Then you should be able to reinstall Unity to restore the graphics.lspci -v
show anything different to what you normally expect? I will add my comment as an answer anyway
