I can't upgrade from 11.04. I've disabled all apt sources, but still I get:

Synaptics screenshot

The only option I am capable doing is to format and reinstall whole system, which I don't prefer as I have tuned a lot of apps settings, etc.

How can I fix this?

Update: After restart, when trying to update all packages, I get this error:

installArchives() failed: dpkg: error processing flashplugin-nonfree (--remove): Package is in very bad, inconsistent state - before trying to remove rather reinstall it.

Reinstalling it results in the same error.


I found a solution at :

sudo rm /var/lib/dpkg/info/flashplugin-nonfree.prerm

sudo dpkg --remove --force-remove-reinstreq flashplugin-nonfree
sudo dpkg --purge --force-remove-reinstreq flashplugin-nonfree

But after doing that, the result is still the same.

Update: Should I do what I found?

for pkg in `dpkg --get-selections | awk '$2=="install"{print $1}'`;
  do sudo apt-get install -y --reinstall $pkg;

Seems it's time to install from a scratch... – Ondra Žižka Oct 16 '12 at 4:38

Did you try sudo dpkg --configure -a. Also, you can try sudo apt-get update --fix-missing, it's a very basic answer, but it may help.

Maybe you should try dpkg --get-selections | awk '$2=="install" { system ("sudo apt-get install -y --reinstall " $1) }, from what I read and understand (I'm not a native English speaker) , it will reinstall all the packages, and It will take a very long time, but it's worth trying it (I read it on the link you provided). – Alex Spataru Sep 22 '12 at 21:16
