I'm fairly sure this isn't a duplicate of bug 911706. Bug 911706 is not about computers that aren't connected to the Internet; it is about computers that are connected to the Internet without using Network Manager.
Judging from the linked tutorial, the fix for this bug is to enable the "Install" command not just if there's an Internet connection, but also if there isn't an Internet connection but the selected package is from a file:/// repository. ** This bug is no longer a duplicate of bug 911706 USC relies on NM to be online, can't force online if not using NM -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to software-center in Ubuntu. https://bugs.launchpad.net/bugs/1014277 Title: Ubuntu Software Center does not installing packages from Local repository Status in “software-center” package in Ubuntu: New Bug description: Ubuntu software center is not able to install packages from local repository as this question in AskUbuntu.com suggests: Link http://askubuntu.com/q/137426/61218 I have a Local repository, created to avoid re-downloading of packages. It is a trusted repository, so no "Authentication errors" are there. I've tested it with synaptic and apt-get. But I don't want to install synaptic every time, I install Ubuntu (since synaptic is removed from default Live CD since Oneiric). The problem is : "Ubuntu Software Center" does not install packages from local repository. The install button is greyed out. It installs packages only when I connect to the Internet and for some unknown reason it re-downloads the packages which are also in my Local repository. My question is: How can I use Software-Center to install packages from local repository ? Note: I have placed my local apt line to the top of the sources.list file and installing from `apt-get` do not require re-downloading for the same packages. Here is the output of command from apt-get : anwar@Ubuntu:~$ sudo apt-get install nautilus-wipe --print-uris [sudo] password for anwar: Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: nautilus-wipe 0 upgraded, 1 newly installed, 0 to remove and 131 not upgraded.

Ubuntu Software Center is not happy with the local copy, below is the output ![enter image description here][1] The install button is grayed out. Why?
