Remove obsolete repositories form sources.list



This question relates to Ubuntu 18.04, Bionic The OP added, by mistake, an obsolete repository for Ubuntu 12.04, Precise, which has reached the end of its life. This obsolete repository does not exist any more and results in the error:



E: The repository 'http//archive.canonical.com precise Release' is not signed. 


The solution is to remove the offending line from sources.list.



GUI method:



Open the program "Software and Updates"



enter image description here



Then go to the Other Software tab:



enter image description here



Find each line that has precise on it. Highlight one line at a time. Press the Remove button at the bottom of the window.



Repeat for all lines with precise on it. These lines refer to obsolete repositories for Ubuntu 12.04. You are using Ubuntu 18.04, one of the currently supported versions.



Command line method:



Open a terminal by pressing Ctrl+Alt+T and type:



sudo nano /etc/apt/sources.list


Now you will be able to edit the sources.list file. Look for the line:



deb http://archive.ubuntu.com/ubuntu precise Release


Delete this and any other line with precise in it.



Exit nano editor by pressing Ctrl+X. The editor will prompt you to save the changes. Press Y and then press Enter to select the default file name.



Hope this helps
