My OS is Ubuntu 13.04

Recently something had happened with Pacakage Manager and its giving issues when i try install some software.

If i try to install from Ubuntu Software Center, it says

Requires installation of untrusted packages

This requires installing packages from unauthenticated sources.

And if try to install from console it says:

apt-get install ipython
Reading package lists... Done
Building dependency tree      
Reading state information... Done
The following packages were automatically installed and are no longer required:
  libc-ares-dev libev-dev libev4 libjs-node-uuid libssl-dev libssl-doc libv8-3.8.9.20 libv8-dev
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
  python-decorator python-simplegeneric
Suggested packages:
  ipython-doc ipython-notebook ipython-qtconsole python-matplotlib python-numpy python-zmq
The following NEW packages will be installed:
  ipython python-decorator python-simplegeneric
0 upgraded, 3 newly installed, 0 to remove and 0 not upgraded.

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I followed the accepted answer at Requires installation of untrusted packages? and now situation is worse then earlier :(

Now if try to install something from console it says:

apt-get install ipython
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ipython

Please suggest a solution.

  • 13.04 (Raring) is no more supported. So it is no more present on the mirror you are using (404 error). You can check by opening the URL in a web browser, you will see that there is no more raring directory on this mirror. So you should upgrade to a supported version like 14.04 LTS. – Benoit Aug 08 '14 at 09:26
  • yeah, i know that but i thouht that no more supported means no updates will be pushed to 13.04, i should never get 404, it means they have delete the repos? Please correct me? – MA1 Aug 21 '14 at 07:03
