The Package System is Broken after Upgraded to Ubuntu 17.04

After upgraded my Ubuntu to 17.04, the package system is broken. When I execute any of the following commands, I got some error.

sudo apt-get --fix-broken install

$ sudo apt-get --fix-broken install

Use 'sudo apt autoremove' to remove them.

I also have tried the following solutions but they did not work.

Anyone know how to fix it without reinstalling Ubuntu?

Answer 1

I think I found a solution, but a big caveat though: it works, but I can’t explain why.

First, I went to /var/lib/dpkg/info/:

cd /var/lib/dpkg/info/

Then, I removed the lines pertaining to the packages which caused the problems. In my case, I had to do:

sudo rm -r python3-apparmor-click.*
sudo rm -r click-apparmor.*
sudo rm -r click.*
sudo rm -r ubuntu-app-launch.* 
sudo rm -r url-dispatcher-tools.*
sudo rm -r url-dispatcher:amd64.*
sudo rm -r libunity-scopes1.0:amd64

After that, I typed:

sudo apt purge python3-apparmor-click
sudo apt purge click-apparmor    
sudo apt purge click
sudo apt purge ubuntu-app-launch
sudo apt purge url-dispatcher-tools
sudo apt purge url-dispatcher:amd64
sudo apt purge libunity-scopes1.0

After that,

sudo apt update

And finally,

sudo apt dist-upgrade

which worked and updated my packages. All the packages problems seem to have disappeared.

Answer 2

I had the same problem after upgrading to Ubuntu 17.04, this worked for me:

sudo -H pip3 uninstall click
sudo apt install python3-click-package
sudo apt upgrade
sudo apt autoremove

Not sure why (perhaps pip's click version is different than the one Ubuntu depends on?) but this fixed the issue.

Answer 3

First remove python 'click' package using pip:

pip uninstall click

If you using python3 : pip3 uninstall click

Then fix the packages by apt:

sudo apt clean
sudo apt install -f 

Answer 4

This seemed to solve the problem for me (at least I do not get error messages any more):

I did a sudo apt autoremove and noted the packages with unmet dependencies:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 bind9-host : Depends: libdns162 (= 1:9.10.3.dfsg.P4-10.1ubuntu4) but 1:9.10.3.dfsg.P4-10.1ubuntu1.4 is installed
 dnsutils : Depends: libdns162 (= 1:9.10.3.dfsg.P4-10.1ubuntu4) but 1:9.10.3.dfsg.P4-10.1ubuntu1.4 is installed
 gnome-software : Depends: gnome-software-common (= 3.22.7-0ubuntu3) but 3.20.1+git20170208.0.a34b091-0ubuntu1 is installed
 gvfs : Depends: gvfs-daemons (>= 1.30.4-0ubuntu1)
 gvfs-backends : Depends: gvfs-daemons (= 1.30.4-0ubuntu1)
 gvfs-daemons : Depends: gvfs-libs (= 1.28.2-1ubuntu2) but 1.30.4-0ubuntu1 is installed
                Depends: gvfs-common (= 1.28.2-1ubuntu2) but 1.30.4-0ubuntu1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Then I went to http://packages.ubuntu.com/ and in the 'search' para entered the names following 'Depends: ' and selected 'zesty'. Then I downloaded the .deb files for my hardware.

Next, I moved all the .deb files to /var/cache/apt/archives:

sudo mv *.deb /var/cache/apt/archives

Lastly I did:

sudo apt --fix-broken install

which executed without errors

• Option 1: Look for the this foreign click package:

  sudo updatedb
  locate -ir python.*click
  

  Then delete it manually, add the output to the question if you are in doubt.

• Option 2: If you are still at that state mentioned in th e question:

  Preparing to unpack .../click-apparmor_0.3.18_amd64.deb ...
  Cannot start click due to a conflict with a different 
    locally-installed Python 'click' package.  Remove it 
    using Python packaging tools and try again.
  dpkg: warning: subprocess old pre-removal script returned error exit status 1
  

  1. Remove the installed package

     cd /var/lib/dpkg/info/
     sudo mv click-apparmor:amd64.prerm click-apparmor:amd64.prerm.backup
     sudo dpkg --force-depends -r  click-apparmor
     

  2. Try install the new package using:

     sudo apt -f install
     

     Add the new error if any to the question.
