Packages are not available for installation
- by Alex Farber
Changing some Software Update settings I possibly corrupted something, and now I don't see many packages in the list. For example:
alex@u120464:~$ sudo apt-get install codeblocks
[sudo] password for alex:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package codeblocks
I checked all options in the Software Sources dialog, but packages are still not available. How can I fix this?
OS: Ubuntu 12.04, 64 bit.
Additional information.
alex@u120464:~$ sudo apt-get update
[sudo] password for alex:

Ign http://archive.canonical.com precise InRelease

Ign http://archive.ubuntu.com precise-updates InRelease
...
It looks like most Ubuntu repositories are not searched, how can I restore default update behaviour?
