One of the older post described how to fix the infamous “Problem with Mergelist” error when trying to install applications in Linux Mint/Ubuntu. It involved using a couple of commands from the Linux Terminal to get rid of the error.
In Linux Mint 15, there is now a simple option that will fix this error all with just a few clicks. So there is no need to type in all those commands if not interested. 🙂
Here is how :
Open Preferences > Software Sources.
Go to the “Maintenance” tab and click on “Fix MergeList problems”.
A notification will then pop-up requesting to reload the cache.
Click the button “Update the cache” which will now be available on the top right of window.
This will start a fresh download and update all the software repositories , also then will check to see if system is updated with latest version of installed applications.
