I've recently upgraded my Ubuntu to 16.04 LTS. While trying to install some programs (in particular, Okular and Amarok) from the console, I get variations of the following error (my Ubuntu is in Spanish, so I'll post the English version of the error that I found online):

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
okular : Depends: libokularcore7 (= 4:15.12.3-0ubuntu1) but but it is not going to be installed
      Depends: kde-runtime (> 4:4.10) but but it is not going to be installed
      Depends: libkio5 (>= 4:4.14) but but it is not going to be installed
      Depends: libkparts4 (>= 4:4.14) but but it is not going to be installed
      Depends: libkprintutils4 (>= 4:4.14) but but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I've tried fixing broken packages with Synaptic, apart from several commands that according to the internet (in particular this tutorial) might help, but none did:

sudo apt-get -f install

sudo dpkg --configure -a

sudo apt-get clean

sudo apt-get autoclean

...etc

This is the result of running cat /etc/apt/sources.list :

Anyone got any ideas?

UPDATE: I'm adding the result of running cat /etc/apt/sources.list.d/* , in case it's of any use.

Try to comment out these lines from file /etc/apt/sources.list:

deb http://archive.canonical.com/ubuntu trusty partner
deb-src http://archive.canonical.com/ubuntu trusty partner

(3-rd and 4-th from the bottom)

Then:

sudo apt-get update
sudo apt-get install okular

EDIT

After reviewing what is in your /etc/apt/sources.list.d/* I would suggest to get rid of:

deb [arch=i386,amd64] http://linux.dropbox.com/ubuntu wily main
deb [arch=i386,amd64] http://linux.dropbox.com/ubuntu wily main
deb http://dl.google.com/linux/talkplugin/deb/ stable main
deb http://deb.opera.com/opera/ stable non-free

(basically anything non-xenial)

Then again try sudo apt-get update and sudo apt-get install okular.

  • Doesn't work. =( I get the same "unmet dependencies" and "you have held broken packages" error as before. I added results of running cat /etc/apt/sources.list.d/* , just in case. – ssinyam Feb 18 '17 at 03:30
  • "Get rid of" implies commenting out those lines, right? I did that and once again it didn't work... Tough one, ah? Thanks for your help! – ssinyam Feb 24 '17 at 23:50
