Unable to install and remove software

[MUK3SH]

Sorry Guys It May repeated post.
I tried search But didn't find any better solution (Or the Noob don't Know how to search.)


When i am installing any software from software center I am getting following error.

The installation could have failed because of an error in the corresponding software package or it was cancelled in an unfriendly way. You have to repair this before you can install or remove any further software.

Please some one Give me an solution.


Thank You

Hello MUK3SH

Welcome to the Forums.

Open a terminal (Ctrl+Alt+T) and run the following commands one at a time.

sudo dpkg --configure -a

sudo apt-get install -f

sudo apt-get update

sudo apt-get upgrade

Hopefully this should fix things.

If it does not post the error messages here between

tags by clicking the # button.

Thank you.

One possible reason for this issue can be your source /etc/apt/sources.list got corrupted.
If this the case then please verify this file and then delete it.

This will update you software repository list to default one, possible this happens when you have added some invalid software repository.

After deleting that source list, run below command, hope it will work for you.

sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade
