Ubuntu – How to fix “Package is in a very bad inconsistent state” error


I can't update my system because it freezes while installing a third-party update (zramswap-enabler)!

Sometimes I get the following message in Update manager:

Could not initialize the package information An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

E:The package zramswap-enabler needs to be reinstalled, but I can't find an archive for it.

I tried to remove the zramswap-enabler, but it's impossible because I get the following message:

dpkg: error processing zramswap-enabler (--remove):
 Package is in a very bad inconsistent state - you should
 reinstall it before attempting a removal.
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Actually I would really reinstall that package, but it is unable to do it! If I remove this third-party PPA then the system is warning me about a very very serious problem.

So why can I not install/reinstall/remove/update this package and why freezes the updater if I try to update?

Edited out of the question and added as an answer.

  1. Make sure that your PPA is set up.

  2. Remove the broken package via the following command:

    sudo dpkg --remove --force-remove-reinstreq zramswap-enabler
  3. Install the package again:

    sudo apt-get install zramswap-enabler
  4. After restart (not necessary), you are able to install the updates correctly!

Actually you can fix any "Package is in a very bad inconsistent state” issues with this solution!
