Changing some Software Update settings I possibly corrupted something, and now I don't see many packages in the list. For example:
[email protected]:~$ 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.
[email protected]:~$ sudo apt-get update [sudo] password for alex: Ign http://extras.ubuntu.com precise InRelease Ign http://security.ubuntu.com precise-security InRelease Ign http://archive.canonical.com precise InRelease Ign http://archive.ubuntu.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?
