Adding Main Repositories

**MartianTek3** · October 2nd, 2013

Hello,
I recently just upgrade to 13.04 64bit (from 12.10) but ever since then installing PPAs have become a nightmare.

After

Code:

sudo apt-get update

I received this:

Code:

W: Failed to fetch bzip2:/var/lib/apt/lists/partial/extras.ubuntu.com_ubuntu_dists_raring_main_binary-amd64_Packages  Hash Sum mismatch

W: Failed to fetch bzip2:/var/lib/apt/lists/partial/extras.ubuntu.com_ubuntu_dists_raring_main_binary-i386_Packages  Hash Sum mismatch


W: Failed to fetch bzip2:/var/lib/apt/lists/partial/ppa.launchpad.net_linrunner_tlp_ubuntu_dists_raring_main_binary-amd64_Packages  Hash Sum mismatch


E: Some index files failed to download. They have been ignored, or old ones used instead.

Also in Synaptic this message:

Code:

 E: The value 'stable' is invalid for APT::Default-Release as such a release is not available in the sourcesE: _cache->open() failed, please report.

I believe the problem is that I deleted the MAIN repository (Canonical) for 13.04 Screenshot from 2013-10-02 22:16:23.jpg

Goal: To find answers to restoring the PPA so that I can install TLP(power manager) and other software

My guess is that your link to the repository of the PPA is incorrect. It is always best to remove any PPAs before Upgrading to avoid issues like this. From the Launchpad page ofr this PPA i see this

deb http://ppa.launchpad.net/linrunner/t...-extras/ubunturaring main
deb-src http://ppa.launchpad.net/linrunner/t...-extras/ubunturaring main

https://launchpad.net/~linrunner/+ar...hinkpad-extras

If you open the Ubuntu Software tab in that utility you may see that the Main repository is still there. See, the tick mark against Canonical-supported free and open source software (main).

Regards.
