Version problem with "click" package after upgrade to 15.04

[iscott2]

After upgrading my Ubuntu Gnome from 14.10 to 15.04 I had a bunch of problems with package configuration and version dependencies. I was able to fix most of these by purging the gnome3-team/gnome3 ppa and doing "sudo dpkg --configure -a" and "sudo apt-get -f install" a couple of times.

Now the only packages that have problems are "click" and "click-apparmor". When I try to do "sudo apt-get upgrade" I get this:

The following packages have unmet dependencies:
 click : Depends: python3-click (= 0.4.33) but 0.4.38.5 is installed
         Recommends: ubuntu-app-launch-tools but it is not installed or
                     upstart-app-launch-tools
 click-apparmor : Depends: python3-apparmor-click (= 0.2.11.2) but 0.3.8 is installed

But when I run "sudo apt-get -f install" to fix the dependencies, this is the error I get:

I've tried just installing the correct package versions like this:

sudo apt-get install python3-click=0.4.33 python3-apparmor-click=0.2.11.2

But I'm told that the specified versions can't be found for either package.

I'm really stuck. Any help would be greatly appreciated!

I found a deb package for the specified version of click and tried to install it like this:

sudo dpkg -i click_0.4.33_amd64.deb

But I got a similar error message:

I found the solution in the comments on this bug: https://bugs.launchpad.net/ubuntu/+s...k/+bug/1386354

I first had to uninstall the click python libraries using pip:

sudo pip3 uninstall click

Then I ran "sudo apt-get -f install" and the click packages upgraded fine. My package system is working again.
