package deja-dup 34.2-0ubuntu3.1 failed to install/upgrade: package is in a very bad inconsistent state; you should reinstall it before attempting configuration

@mohan:

Have you tried doing what APT suggests: reinstalling deja-dup, which is apparently "in a very bad inconsistent state" (possibly because something failed during your system update on 2017-04-11 11:02:02, although I don't know what did)?

For instance, from the command line:

  sudo apt-get install --reinstall deja-dup

You may also want to check next if there are broken dependencies:

  sudo apt-get check

And fix any broken dependencies with:

  sudo apt-get install --fix-broken

Before upgrading your system again:

  sudo apt-get update
  sudo apt-get dist-upgrade

Also, instead of removing the battery to shutdown your laptop when it freezes, you can try switching to a virtual text console with Ctrl+Alt+F1 (or F2, F3, ..., F6). Explore the process list with commands such as "ps", "ps aux | more", "top" and kill whichever process you can identify as a cause for the freeze with "kill <process ID>", "kill -9 <process ID>", "killall <name>". Then go back to the graphical interface with Ctrl+Alt+F7 to check if it's unfrozen.

If that fails, you can try restarting the graphical session with "sudo service lightdm restart" in a virtual text console.

And if you can't even get to a virtual text console, you can try powering off your laptop by long pressing the power button instead of removing the battery. That works on many laptops.

thanks

I'm converting this bug report to a question, as it doesn't appear to be a bug in Déjà-Dup (upstream or package), but a support request after an installation failure.

Please comment and/or convert the question back to a bug if more help is needed and/or more information can be provided and/or it turns out to be a bug.
