I first run sudo dpkg --remove jenkins and I get a response : 

dpkg: error processing package jenkins (--remove):
package is in a very bad inconsistent state; you should
reinstall it before attempting a removal
Errors were encountered while processing:
    jenkins

So I then try with sudo apt-get --reinstall install jenkins and result is :

Anyone can tell what should I do to fix and update the package ?

  • Try running sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade (last command perform a package upgrade) – Liso Oct 30 '16 at 09:00

You have to add --force-overwrite suffix on dpkg command, this will overwrite file that causing the error.

sudo dpkg -r --force-overwrite (file)

In your case, it would be 

sudo dpkg -r --force-overwrite /var/cache/apt/archives/jenkins_2.19.1_all.deb

Make sure everything is fixed by running:

sudo apt-get -f install

  • Hey thanks for the answer. I tried the first command but it;s not working (error is illegal package name in specifier must start with an alphanumeric character). So I tried sudo dpkg -r --force-ovewrite jenkins but once again I get the message about needing to reinstall package before attemping a removal. – mt0s Oct 30 '16 at 17:37
  • Anyway did you run second command ? Make sure you write the file too, not just jenkins – Liso Oct 31 '16 at 16:52
