I'm unable to update my system Ubuntu 14.04 as software updater isn't running. Also I'm unable to run Ubuntu software center. All these problems arose after I tried to do partial upgrade of my system. I was as such updating my system but it messaged that some applications can be updated only after I do partial upgrade. I clicked on 'partial upgrade' option but it didn't happen successfully. A message was displayed

upgradation message

After that I'm unable to run software updater, Ubuntu software center etc.


This edit is the output of the commands I ran as mentioned in the answer by IcyIcyIce

I ran the above commands twice because 1st time it failed to fetch data. Now also the issue isn't resolved as I'm still unable to open the applications.


This edit is the output of the commands as mentioned in the comment by IcyIcyIce in his own answer.

ravi@ravi-Aspire-5315:~$ apt-cache rdepends libfdk-aac0
Reverse Depends:

@IcyIcyIce Could you make out something what the issue is & how I can proceed now?


Try running the commands sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade || sudo apt-get -f install. If something went wrong, updating the repos, trying to update and if that fails, tries to fix corruptions.

Hope it helps :)

  • please look at my edit in the Q. It didn't work.

  • you could check what depends from that package by running apt-cache rdepends libfdk-aac0. Maybe it could tell us something...

  • I've shown the output of the command in my Q as EDIT#2. Can you make out something?

  • well now I'm lost a bit. I'd definitely try sudo apt-get --fix-missing install or maybe it's without the install... anyways if you get an error saying the command is wrong just type without install. But from the previous post it seems like you can't contact a repo and that's why you can't download the package. Maybe you could try going to software sources and somewhere there you can choose another server to download from. But in this moment I wish someone else looked at this because I'm out of ideas... Hope you can figure it out somehow, if I get an idea I will definitely post it here :)

  • Please look at the screen shot I added now of the messsage I got while upgrading. I think you can get a clue as what I should do now. Is that the issue? How to re-enable them now?
