16.04 Software Updater not working

[elim-qiu]

When installing 16.04, I formatted partition / but keep my account dir in partition /home unformatted so that I can keep my user data there.

Most things runs well but for some reason my Software Updater not working:

I did installed midori, but for some reason that made Software Updater so messed up...

Please tell me how to fix it. Thanks a lot!

Midori is already in the Ubuntu repositories so that would be the version that you have installed. The output of


apt-cache policy midori

would likely confirm it.

Given that it looks like it is the current version, I'd suggest disabling the ppa that you added.


sudo rm /etc/apt/sources.list.d/midori-ubuntu-ppa-xenial.list

or commenting it out..


sudo nano /etc/apt/sources.list.d/midori-ubuntu-ppa-xenial.list

and place a # sign at the start of any lines that don't already have it. Save out and close with Ctrl + O. enter and Ctrl + X.
